I know the tune is very important but some times you just get a weak motor
why one motor can run at 500+ stock all day and another motor drops off at 450 is anyones guest
my motor died doing a dyno session with a stillen kit and yes it was a money pit to get fixed
now the tune i got from vsr motorsports ran flawless even thought we did have some other small problems. and the turbo kit has been great
