venom 400 pcm

k i no theres been some posts on this before, but im still wondering do they really do nothing at all? i read all it does it makes the car think that your pressing the gas harder but what if you floor it shouldnt it somehow give more power?..or not? i found one for 75 bucks and i was just wondering if its worth it

Yes that's all they do stay away from those and JET chips.
