yeah high 9s in a/f ratio would be rich as hell, which is ALWAYS better than running lean. If he was that far in the other direction from his 11.5 tune then that would be bad. Im getting snow's meth setup probably in another month along with my cxracing h/e and dual pass with option b setup. Once I get that squared away im going to drop down to a 2.7 from a 2.9. With the cooling mods im going to get tuned, then drop the pulley and adjust the tune as needed from there. Should be good to go then!
Try lowering your AFR in PE to 11.8 at about 3k rpms and work up to your 12.1 at 5k and up. You might like it.

don't give it all away

i love it when people don't have a clue what they are talking about, jump into a conversation without any background or personal use of it.
pimp. wrong answer bud.

Besides, I've not had a chance to try that yet with meth. Just going with my limited knowledge of physics. I was hoping he would try it and tell me if it works.
Oh, and I hope you won't be running that 2.7 on stage 2 injectors. Even with meth, you'll **** them off in a very unpretty way.

But if I let everyone do whatever they wanted, people would be blowing up cars and I would have nobody to send me PMs all the time and...
Hmmm... Never mind, run meth without tuning. Oh and max out your IFR table at 63.5 and... and... and... zero out your adders... and... and... and... bounce your car off your rev limiter... and... and... and...
***sigh***
dont know numbers. i run the ais kit
meth does cool yes. but adds horsepower when you tune for it. you pull timing... more hp

Rich adds torque, lean adds HP. Where is our torque curve the strongest? Where is our peak HP? I've done 11.2 low - 11.7 high with decent success, but without access to a dyno, it's just speculation. The one chance I got to dyno, I pulled a lot harder commanding 11.4 low than commanding 12.4 low and working down to 11.5 (like most want to do it). The bad thing is the dyno kept flipping out at around 5000-5500rpm (iirc), so I got no reading above that. Car definately likes rich down low though.
