One of the fastest cars I've seen was running PFS piggy-back.

I don't know who in CA can help you. You don't necessarily need to dyno the car to optimize the computer, but you haven't indicated the condition of your engine. Has it got good compression nos., clean plugs, no vacuum leaks, and a stock turbo unit that isn't worn out? The engine and bay ought to be clean and you need a hi-flo air intake.

What other mods have you got?

 

Wade Lanham is the expert on that box. See http://www.wvinter.net/~flanham/wlanham/

 

it's really easy to tune, just read the manual.
