Procharger guys with meth- what timing are you running? I've had my meth kit on and been using it ever since I put the F1 on (still have the P1 tune when I wasn't using meth). I am going to be getting it tuned in a week and I'd like to know what timing everyone is running when using meth. Right now, I am at 20° and no KR. How much more (if any) should I go up from there? So for you supercharged guys out there using meth, what is your timing?

Too many variables bro-but i'm running 16 degrees up top. Just make sure your knock tables are stock-FWIW I really only use the Alky to drop the inlet temps. They go from 120 to 70-80 degrees at 20 psi.

Bro-your going to have to put the car on a dyno and just keep adding timing until the gains are just not worth it-just watch torque and horsepower-2 degrees extra maybe worth 30 rwhp-add another 2 and it may only add another 15 on top of that-when that happens call it day and settle on the 2 you first added-it's always better to play safe. Keep the tune fat at 11.1-remember that if the meth fails your AFR will raise 1 point-just keep that in mind. I log IAT temps witht the meth so my nozzles are before the sensor-you can mess around with the computer to set IAT retard tables then.
Guess its a case by case basis... I just wanted to know what everyone else was running so I could get a feel for the ballpark...
