I think you want to take it to someone and have them dyno tune it... a mail order tune sounds like it would be tough for your setup.

U can't run 22psi from 88mm turbo with 8.6 C/R and pump gas. Check EFILive.com Forums for better help. U will need to buy their software with 3 bar Speed Density tuning.

Good luck.

not only that, but if that cam is 287, on a STOCK cubed motor, I think that thing would HATE boost.

Good luck with the tuning.

That cam is advertised by Comp Cams as designed for large cubic inch LS1/LS6 engines, race only.

You would be better off with 54-444-11 or a custom grind cam. That thing will take forever to spool the turbo.

Did you try HP tuners for tuning with the MAP sensor. A dyno tune would be your best bet for that amount of boost.

Also, what rear gear ratio with the TH350 to help spool the turbo?.
What type of injectors?
What fuel pump? Any fuel system upgrade? I hope not stock fuel pump and system for that amount of boost.

Good luck.
