·I recently dynoed my car on mostly pump gas and made 575rwhp and 500rwtq with fairly conservative tuning, which I thought was pretty good. That's stock cams, stock intake, etc. Today, I filled my tank with straight 110 leaded Sunoco Turbo blue and even at 28 psi I couldn't make 575 rwhp! Also the turbo was hitting max boost over 700 rpm later!! I increased the timing quite a bit, until the point where the power stopped going up, but the power was still very low. The car appears to be running awesome other than the low power. During the dyno, it didn't knock even once and the EGT's were quite low. I've had the same problem in the past... whenever I ran more than 50% leaded gas the car just felt dead. I assumed it was because I used to run the stock ECU and it was being stupid... but I have full control over timing now with my AEM. I had the a/f up to 12.5:1 and the timing up to 16 degrees at high boost and it wasn't giving me any more power. People are telling me 100% leaded gas should work just fine, but I'm not convinced. Does this gas just suck or what the heck is going on? My compression is precisely perfect.
