This turbo has time and time again made well over 600 whp with high boost. Granted its ^making great power at low boost, just small power band.
Maybe the turbo and setup is not in it's efficiency range yet. That or the tune needs brush up.
No boost leaks bcz I am paranoid and always check couplers lol
Again, we ran out of fuel and Nate never even messed with the timing map before he lowered the boost down to 21psi(which I am driving the car on right now).
For comparison, since I go to Wyotech, I have easy access to an AWD DynoJet so here are some numbers and graphs to compare my low boost maps(21psi):
I know you guys love comparing dyno numbers :-)
