It seems to be the norm to say max safe power on a stock bottom end is 400-450ish with a good tune. Now. My Vortech v2 2v is at 382rwhp with a SAFE tune. Tuner told me there is a lot more in it. This was on a dynojet, which do read quite high. So, is this max safe level on a mustang dyno, or dyno jet? Very different numbers. A guy I know has almost an identical setup and he has been at 450ish on the same dyno for 2 years. So what is it? Dynojet or Mustang Dyno?
