I was not talking about maximum, sorry if u took it the wrong way. I was just suprised that the guy wrote so much about these evil ppl. It doesn't take much to figure out thats bs. I also wasn't saying that cheap on e-bay is bad. I wanted to make a point that u can't gain 20hp for $20 , ever see power pages in import tuner , they spend around $1k to get ~10hp. What I want to suggest to everyone is to shop around at reputable stores and research ur product and then go to e-bay tobuy it. Don't use e-bay as ur source of knowledge couse u will get screwed. If u find a "mod chip" on e-bay try looking for something like that at reputable stores. 9 out of 10 u won't find it anywhere.
