I think before you start throwing money at the car, you should step back and think on this. If you look at the slip I posted above, your car is low mph in the 1/8 and the ET should be lower I think. IMO....
1) Make sure you are not running with TCS on
2) Make sure your car is shifting at the right rpms for your combo, maybe some quicker blowered guys can suggest what they use.
3) Your short times should be at least 1.8's. Make sure you are getting real heat into those tires, and make sure you are lining up in the groove. Are you spinning or does it dead hook? You need to know.
4) Fix whatever is not right.
Go back. Repeat.
