www.SLRmotorsports.com i recently bought an SLR computer chip.. I receive the so calle chip with some connectors and wiring code instructions. wiring coe int match my veh.i trie to contact SLR numerous times for instruction unknown, Florida

I guess you were unaware that these "chips" don't do a thing to help performance? So the fact that the diagram did not match your vehicle is irrelevant. There is no such thing as a magic chip at any price that does anything. Your vehicles ECM is already optimized at the factory to allow your vehicle to run at it's peak performance and fuel economy..otherwise they would use the chip..right? And that is not even considering this company is claiming a special chip programmed for your specific application..and all they ever send anyone is a basically a resistor in a box. Fraud.

You are not the first person to fall for this. And there are other complaints about this company here on this site and all over the internet, I am surprised you missed it. All the same complaint as yours basically.

Keep in mind that placing a resistor on anything or tampering with sensors could damage your engine or systems at worst..and do NOTHING at best. Regardless of the lies you read on their website.

I would lodge a complaint with the FTC and let them know you were defrauded. I am actually surprised this company is still in operation, they have been scamming people for some time now. If this company gives you a refund just because you are requesting it (assuming they even respond), it would be a small miracle.

A word of advice as well. Almost any 100% money back guarantee is a sign of a scam. Have you ever heard of one that actually gave money back? Another factor is even if they were to work with you and communicate with you..they would refuse to refund anyhow. They would tell you they only honor the guarantee if you install it and use it for a while and are unhappy with the results. (read the wording on their policy more closely, this is what they would tell you if you ever got to speak with them). Since you can't even install it and would need a different diagram sent to you..well I think you get the idea. You fell for their deceptive claims hook, line ,and sinker.
