You could move the cam back to 0 to pull some of the torque out down low and give you a better run on the top end.... or you could just put in a programmable 7 MSD box to add timing in after the launch

Like the others have said... lower your tire pressure and also stiffen up the shock(extension). Take a video of your launch... you'll learn alot from the video

Yep, tire pressure! Compression is low for that intake port, and cam will not really "use" that head the best it can!! You have alot left on the table for sure. Brian
