Get my car to launch better...

Here's an update from my last post. I moved the battery to the trunk, drag shocks front and rear, installed a mallory hyfire with 2 step limiter and a line lock. While going down the strip, I was unable to keep the throttle to the floor the entire time, since I ended up having problems shifting the tranny doing that (wouldn't go into gear sometimes). I finally got decent at burnouts and I tried launching at different RPMs. At first I tried launching at 2500 (using the 2-step) and the tires hooked, engine bogged and took off. 60' time was 2.00. Kept bumping up the 2-step and kept improving times slightly. On my last pass I set the 2-step to 4000, dumped the clutch, tires hooked, bogged slightly and made a 12.97 pass with 1.91 60' time (Previous best was 13.19 and 106MPH). My MPH was 107.17, also the fastest of the night. I think I'm going to try bumping up my 2-step RPM even more next time, I don't want to break anything, but I don't think I'm at the power level right now to start destroying u-joints or the rear end anyway. Thanks for the help everyone. I finally got my tires to hook off the line, and I've got my street car into the 12s.

Best part of all I beat my buddy in his attempt to get his AWD Jeep SRT8 into the 12s (his best was 13.01 despite all of his money spent on computer tuning and car payments). You should have seen his frustration!
