hey everyone.. i have seen ppl on here several several times say "not to buy the jet ecu upgrade" but i was just being curious.. what actually do they do wrong?? i mean compared to what JWT or TS offers?? i have a 97 and no one else offers one.. i know that a 96 will work also.. but i just wanted to know what the ACTUAL difference was.. in why everyone always dogs them.. plz DO NOT POST *****.. i know that eveyone is going to want to post and tell me that they are just pieces of crap.. and dont buy one.. i already know that.. i want to know "technically" what is supposed to be different.. that they do wrong or even dont do compared the others on the market.. in advance thanks to anyone that can shed some light on the situation..
