not totally true, it will work at wide open throttle, with proper tunign of course. After i researched it i figured that it would not be a worthy mod since you should have a shop professionally do it, cause they can tune the device with a dyno and a very accurate A/F ratio gauge. you can try to street tune it yourself but it can be dangerous if you set it wrong, and you problably won't get it to it's full potential. that thing costs about $200 but tuning is like $500 so for me it was not worth it. oh and BTW the CPU is in the engine bay, right above the fuse box, it says "do not remove" on it.
doesn't work, theres a member on n c org who did 40 or so pases on it and after 2 or 3 runs it would reset back to stock.
choose to belive it or not, it just doesn't work.
