I recently purchased a new 2013 BMW 550IX and after researching Dinan's website, DinanCars.Com and speaking to two Authorized  Dinan dealers in MA discussing the Stage 1 software upgrade ($2,999)  I decided to move forward.

Dinan’s website mentions an incredible increase from 400 HP to 495 HP and an increase in torque from 425 to 573 ft lbs.  This sound pretty impressive!

My complaint or review is that my results were DISMAL to say the least.  My Dinan upgrade resulted in ONLY an 11 HP increase and ONLY 17 ft lbs of torque.  I was not ripped off for my money as it was refunded. 

I was however ripped off for all my time and added expense that I will further explain.

I decided to have the upgrade performed at Dinan’s authorized dealer, The BMW Gallery in Norwood after speaking three if not four times with Steven Richards who is the designated technician that does the Dinan Stage 1 upgrade. 

He informed me he had done many of these and reiterated the increase from the mfg specs of 400 HP to 495 HP and the torque from 425 to 573ft lbs MANY, MANY times!

When I asked him how I would ever really know what the actual gain was he advised me to go to Kaizen Tuning in Boxborough to have a dyno test to first determine my present HP and torque and then return there for a follow up test AFTER the Dinan upgrade to confirm the incredible increase.

I did exactly as he advised. On Sept. 13th, 2013 I drove one hour to Kaizen and paid $175.00 for a dyno test. 

The technicians at Kaizen Tuning explained to me as well as Steven Richards had that the true numbers of HP and TQ would be less than what the manufacturer claims in the specs. The manufacturer uses data of HP and TQ derived with the engine sitting on a “dyno frame” whereas the actual true HP and TQ is at the wheels.

 The dyno testing resulted in 336 HP and 350 TQ.

The following day on Friday Sept. 14th I had the Dinan Stage 1 upgrade performed at BMW Gallery in Norwood, Ma.   The upgrade or download as they call it took a couple of hours.  I might ad Steven Richards again reiterated the claim of an increase of 400 HP to 495 HP and the torque from 425 to 573ft lbs.

The following Tuesday Sept. 24th I now returned to Kaizen Tuning and had the Dyno test again performed to confirm the increases 

The results were: 347 HP and 367 TQ.     This translates to an increase in power AFTER the DINAN stage 1 of       ONLY 11 HP and 17 TQ.    Certainly an incredibly dismal increase after all the bro-ha-ha regarding their claims

When I called Steven Richards at Norwood his first reply was Kaizen's graphs were flawed. I also spoke to Scott Leandres, Regional sales manager for Kaizen.  He also reiterated very strongly the absolute increase In HP and TQ Dinan claims.

Scott McIver of Kaizen Tuning informs me he personally spoke to Steven Richards and stated his dyno results are not flawed.  He categorically and unequivocally stands by his results and stated just this on his letter head that I have.

What took place these last 9 days is Steven Richards promising me he'd get back to me and each time not hearing from him I would initiate the call.  He finally informed me that either they would refund my purchase 100% or I could bring the car in for TWO days of testing. 

This "testing" was described as a boost test.  Steven Richards told me the boost was originally at "9" and after the upgrade it should have been 14 or 15. 

I again called Scott McIver at Kaizen and he informed me that although not a perfect science each incremental increase in boost should produce 10 more HP.  He adamantly stated that if I had gotten that claimed increase in boost it would have reflected on the graphs. 

Scott McIver of Kaizen Tuning will not budge nor negotiate his stance that my total power increase was ONLY 11HP and 16 TQ AFTER the Dinan upgrade.

Today I left a message with Steven Richards stating I would be amenable to a boost test or whatever else he needed to do to give me what I had paid for.

I expect to get what Dinan's website, Their regional rep, Scott Leandres states as well as Steven Richards of Norwood BMW claims the upgrade will produce.

 I did however make it clear he could not have my car for TWO days testing.  I was originally told the actual upgrade takes less than 1 hour. 

I got a call back from Steven Richards explaining they were refunding my payment 100%.  

Thus my complaint is not that I have been swindled or ripped off, but that I spent a monumental amount time and energy on this Dinan upgrade.  Although I have now gotten a complete refund I cannot recoup the  3 hours I originally spent at the dealership, the 8 hours + in traveling and waiting at Kaizen Tuning and the expense of the two dyno tests that unequivocally prove nothing but the incredibly dismal results of the Dinan Upgrade performed at the BMW Gallery In Norwood, Ma.

It was a very far stretch from the claims made on Dinan's website and reiterated by all the representatives associated with this. 

My complaint is this entire project was a waste of my time and energy and seriously makes me question the claims Dinan makes regarding increases in HP & Torque.

The Dinan website is VERY careful not to make any claims of MINIMUM increases in horsepower or torque.  Instead the “language” on their website is:     The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related re-calibration producing a maximum output of 495 horsepower at 5000 rpm and 573 lb-ft torque at 3500 rpm.”

Obviously this is to protect them from any false claims or advertising but everybody you’ll speak to will “parrot” the maximum claim.  MY INCREASE WAS ONLY 11 HP & 17 TQ.  I’m left to wonder how many past or present customers will just believe all the hype, pay for this Stage 1 upgrade and just assume their

Although Dinan “covers their butt” with their website statement I believe it is REASONABLE TO EXPECT more than just an 11HP increase and more than just 17 ft lbs increase in TQ.  Certainly these numbers are incredibly less than their touted “maximum” increase of 95 HP and 148 ft lbs of torque.   I’m left to wonder how many past or present customers will just believe all the hype, pay for this Stage 1 upgrade and just assume they got what they paid for without verifying it the way I did. 

I would advise ANYONE that is considering dropping 3K for the Dinan upgrade to first have a dyno test done and repeat this process after your upgrade.  If you're going to spend 3K you might as well pay for two dyno tests to give you the comfort level that you got what you paid for.  Lastly make sure you use your credit card so you can get in touch with your bank for a refund if your results are as dismal as mine.  I used my Amex and never doubted I would get my money back.  Perhaps BMW Gallery and possibly with a discussion with Dinan decided it would be in their best interest to just make me “go away” and give me a refund.  

I love my new 550IX and was really looking forward to this Dinan upgrade.

Dinan Stage 1 on Stock 550 -- Explaned

AUTHOR: alexchen86 - ()

Well I am very sorry to hear they quoted you some literally appaling gains in power and torque.  There could have been several ways the manager or service adviser whoever refunded you to dodge your retalition for them putting up false accusations.

First off I need to ask is your car completely stock? I don't mean like sport line package or tech package, I mean have you installed any other modification to the vehicle for additional power? Such as down pipes to replace the cheap plastic ones BMW provides, or perhaps a charge pipe, intake, exhaust, headers, etc...

Did Dinan specifically claim those appaling numbers on a stock 5 series or was it a Dinan 5? Because comparing those monsters is like Godzilla versus a mouse.  Don't get me wrong and I mean no disrespect.  I love the 550i as well but it's too much of a family sport sedan for me right now so I went with a 2013 335i Sport Line and had it tuned to stage 2 with a BMW performance exhaust to retain as much stock appearance as possible.

Even with stage 2 from another BMW specialized tuner shop, I am noticing only about 30-35 more hp and torque hasn't improved much either.

Most people get the MPPK or Cobb tunes because they want that little more power and are willing to pay top dollar for peace of mind since these tunes are backed by BMW USA witht the exception of Cobb I believe.

If you do want more power depending on what range you are trying to achieve or what hp on the dyno I'd suggest putting in an oil cooler ASAP first.  The more boost = more trouble. Second I'd go with a down pipe, eventually charge pipe, then if you still feel the brakes are no longer as firm as you want then change brake lines or upgrade them entirely, then upgrade your tires (get rid of those run flats ASAP) do yourself a favor like me and just buy a portable air compressor for cars that plug into your cigarette lighter. After all that you can throw on an intake for a little giggle or a blow off vavle if you're into that. BOV's and intakes barelty do anything performance wise but I would never put a BOV on a nice 550i...a decent exhaust setup with a downpipe and a good tune really is all you need to push another 100 ish hp.

I already blew my charge pressure sensor 2 weeks ago and may have potentially damaged part of the ground on my DME.  BMW's have waaay too many sensors and computers these days!!

Good luck buddy and be safe!
