I got this Racechip half years ago, then i sold my car recently, so i still have this chip tuning. It really did a great job, more horsepower, faster acceleration, less throttle response, I bought this for 675, now i sell it half price 325.
If you interested, please go http://www.ebay.com/itm/161985939373...84.m1555.l2649 check it out.

 

Why would you want a chip that gives you less throttle response. Sounds counter intuitive.

But on a real note, after doing some research and stumbling onto a couple forums, it seems as though people who buy them or who say wonderful things about them have less than 5 posts when they say such things, and will not dyno the car to prove the numbers. Yet it sure looks like they are Racechip sales people. To be honest, it sounds like a sprint booster.

 

I mean the throttle response time.

 

Also i didn't do any dyno to prove it, i'm just telling you what i can feel, if you want to know, do the research yourself, then i'm not force you to believe me on what i said. At last, i'm not a sales person, i just wanna sold my used racechip. Thank you for your reply.
