I've been lurking on here for a long time and have been waiting for my warranty on my 2013 manual 5.0 to go out before i decided to do any serious mods....My warranty is out now therefore i want to pull the trigger pretty soon on a power adder. I've read a lot of threads and i know that on3 is questionable but i have also seen a lot of arguments saying they're much better since they've done their revisions. Currently all i have on my car is a xpipe/exhaust, bama tune, and complete suspension. I want to spend 6k max on the power adder therefore the paxton/vortech/on3 come into play. I plan on going for 600rwhp for the time being and down the road building the engine and going for more. I'm mostly wanting to do the on3s because i've been wanting to go the turbo route but im curious to hear opinions. I understand this is asked a lot but i haven't seen many (or any) threads about the new on3 revisions and choosing them.
