did anybody try to get this, the guy from the place told me that you can get up to a 20 hp gain.

 

I've got it, it was installed on the car by the previous owner. The only good thing is that it removes fuel cut and adds a little bit more aggressive fuel map. The 20 hp is from "safe" higher boost that would've blown your motor without an FCD.

 

Ask the guy what state of tune the car that the chip was designed for was in. If it was written for a stock car, then it probably won't be suitable for a car with a lot of mods. If if was written for a modded car and your mods don't match, again it migt be all wrong. Chips need to be tuned to suit a particular car and its mods. Anything else is just a shot in the dark. That's why some people have great luck with aftermarket chips and others end up with a car that makes no more power, less torque and sucks gas! Always get a money-back guarantee and before and after dyno runs.
