I know this is a little off the original topic, but my car is a LS3 so I can't comment on the tune for the L99. Also I didn't know there was more than one tune from Magnuson, but my supercharger kit was put together on April 30, 2010 if that helps.
On another unrelated event, I did make it out to test and tune night at the dragstrip. I must say there is definately a steep learning curve on learning how to drive this car at the track. The biggest issue now is how to get a good launch. I tried a couple different approaches that either left the car bogging at the line or getting into a wheel hop from getting on it too hard. My best launch was at about 2500RPM. It still had some wheel hop so I couldn't get on it as hard as I wanted to. Another thing I tried was not letting of the throttle when shifting. This seemed to work well for going from 2-3 snd 3-4, but 1-2 was way too violent. I don't think the stock axles would take that too many times. So I went back to letting off for the 1-2 shift.
So just to let you know, my best time was a 12.70 at 113mph, with a 60ft of 2.126 That is running on the stock tires and suspension. Oh and the temp was about 75 with the humidity around 60%. I know my car can do better, so I will be trying again after a few more upgrades and tweaks. The only good thing was I did have the fastest street car there. Even the Mustang GT with a whipple at 13psi and 565rwhp had a best time of 13.66
