AWD ECU tune by Diiirk

That's it. 93 Octane...26.5psi boost. I still don't know if 500 is safe with the stock head etc. Im reading as much as i can on it. I'd love to see if i can get there though.

I think you can get there... Your injectors might limit you but you can push more boost and see what it does. I ran 30 psi on Q-16 on my stock motor and make 494 hp...

Just built and dyno'd at TopSpeed. 433 hp and 364 trq on 23 psi . FP Black , GSC S2 cams , AMS intercooler and upper pipes, Tial BOV , Perrin exhaust and test pipe , 880 injectors , AEM stand alone , springs and retainers and forged internals. My son is in the military and this is a very safe tune for a DD when he gets back . He will drive it for the first time when he comes home this weekend ! Mad Respect for all the guys at TopSpeed in Atlanta !!! Check Out Doug and Cicio at topspeedsales.com !!

Nice! Those are excellent #'s for that boost level. To put it into perspective when I was running the BBK it took 29psi to make 450 wheel on pump gas. Give it real fuel and real boost and it will easily make 500+.

Thanks man! I made just shy of 500 on stock block, 30 psi, and Q-16 so I'm confident it will surpass that.

Kris1410 - Mine was built and tuned in the Atlanta area as well by Mainstream Performance. They do great work and the head mechanic is a close friend of mine.

Did you open her up a little bit on the drive back?

I did but only on wastegate pressure (18psi). Plus I was constantly accelerating/decelerating so it wouldn't stay at the same rpm for a long length of time.

well, I made 556.3, and 506 ft lbs. @ 31psi on a STOCK internal block, and STOCK head minus buddy club 264/272 cams and ARP headstuds, Trust T1-R exhaust, Snow performance methanol, AEM EMS, and a Peakboost GT3076R turbo kit. This was on a Mustang dyno. It was on 93 octane (Shell V-Power). Never had a problem. Also only using a ACT HDSS clutch and Streetlite flywheel. Drove like a stock car until you got on it. The 500 hp goal is VERY attainable with methanol, and NO E-85. Where I live the E-85 isn't even available.

Yea E85 isn't really available down here on the coast either and I'm trying to stay away from methanol.
