I see that you have the big line kit what kind of fuel pump do you have and what is your fuel psi at rest and under load?

At 45psi the drive pressure is closer to 1:1 ratio. I adjusted my wastegate & noticed that it spooled better & heat went down at wot, but the power still feels like it is there. I'm sure that if I tested it on a dyno that I lost a few hp, but now I have less heat & more usable power because I don't have to watch the pyro...just bottom out the go pedal & hang on. I would like to hook up a gauge to test my drive pressures with both settings though to be sure, but it does feel better. Did you notice a faster spoolup after the adjustment?

so far i just warmed it up and took it easy not more than 10 psi / 900 degs. now im letting it cool off for 30-45 minutes and then im gona go put the hammer down! so far im very impressed. its just to bad they dont know how to tap a hole
Go Pack! 14-9 closing in on halftime.

Keep in mind that even down at 40psi, you're still running 4:1 PR on a single charger. VERY few turbos are on the map at 4:1, and almost all of them are BIG turbos.

The map for the S362 stops at a PR of 3.8.

I'd say to keep the turbo under 40psi, but that's just me.. Obviously, real world results trump compressor maps and theories and "paper" stuff.
