Answer
Hi Ethan,

I don't really know much about street cars. Everything I work on is carbureted. However the modifications to intake and exhaust will help, and there's on more thing I can think of that might help, a different computer chip. Now that's ALL I know about it. There are companies that make different chips for different purpoes, but you'll have to search them out for yourself.  I would start by calling the guys at Summit Racing's tech line at 1 330 630 3030, it's a long distance call so you might want to use your cell phone. Anyhow, they should be able to help you further even if they can't supply you with one.

The other thing you can do is work on your suspension to improve your cornering ability. There's a LOT to be gained by making some subtle adjustments in that department. Basically, if you can get through a corner faster, you cn get in faster and come out a LOT faster.  If you'd like to know more about this subject, write back.

Good luck
