I installed both, the controller being a turbosmart t-piece. The controller runs about 14psi without removing the check ball, 11psi modified. After about two weeks of running 14psi the head cracked. I have wound it back now to max 11psi and have done about 8k since with EGT carefully monitored (get an EGT gauge if you are going to play with the boost/fuelling!). Coincidence? Perhaps , but the factory spec is about 10-11psi, so I might just leave it at that.

i got the turbosmart t piece and installed, it is running at 13 psi but goes back to 11-12psi. was running at 10-11psi before i installed it, well getting it tuned help or running a bigger intercooler?

If you do crack a head, I would highly recommend the AMC brand over the genuine.
The Roo.

Yeah, I know, but I had one on the shelf so maybe next time (hopefully NOT!)
