  1. Saab 9000 (1984 - 1998)
    Hey guys, so I had the car on the dyno and did a run to check base boost and it is at 13 psi. I realize my car should be set to 8 or 9 psi. My question is I have a stg 3 ecu and was wondering if I would notice any benefits from the tune if my base boost is way off.

    Hi, I recently replaced my t25 in my '97 9000 CSE because it was sputtering and seemed like it was misfiring. I put in a td04hl-15t and it still does the same thing but it seems that the ecu knows when that misfiring scenario is about to happen and limits my boost to about 8 psi. Anything more...

    Hi everybody I wanted to know what is the relationship between air flow and PSI. For example the stock IC on an aero 9-5 flows 85 cubic feet per minute and turbo boost is 20 PSI, if we change the IC with an other, which flows 120 cubic feet per minute then the turbo don't need to boost so high...
