Nicely done... If you could put some wider race rubber (295/30R19s?) on there and heat them up slightly in the water box, you may get a better launch on that car.

As to the 'bog down' part, that's your ESP (Electronic Stability Program) kicking in. Even with traction control off, the ESP is not completely disabled, but reduced by 80% (I think that's the specs I read somewhere).

Those with a manual gearbox have tried pulling the ESP fuses, but then it forces a 5,000 RPM rev limit (to protect the engine). I'm not sure if that would happen to you or not with the AutoStick as I had mine on a dyno with those fuses pulled and we did a full pull to red line.

Do a search for 'ESP Fuses' if you want to read the majority of material on the subject.

Hope that helps... Cheers!
