Hey guys, so as im sure im not the only one to be planning to be spending my tax return on some goodies for my car, im. going ko4 finally. I tried searching the forum for keyword k04 but it returned no results which i thought was weird. So im wondering which ko4 to go with considering ive seen that the power they can handle brand to brand differs. Im currently looking at IE, which im already tuned with, theirs ranges 330-390hp. HPA states up to 355, UNI says 340 and so on. Im not sure if they are basing these numbers off of the software used to tune their own ko4 or what because it seems for the most part all of these are pretty much the same. Im looking for best reliability and numbers first then fitment, because i think im gonna have a shop install this for me. IE is currently out of stock but ive got some time before the time comes to buy. Let me know what you think. Thanks.
