take it to the track and run back to back runs, changing it 1-2 psi each run till your times start to go up. i think stock is about 43, correct me if im wrong anyone. but an even better option is to get it on a dyno in the hands of a good tuner. esp with all those mods you have planned.

 

Thanks for the info Sacicons, all will be done in spring. Unfortunately there is no track any where near me, and there are no dyno's here that I know of. I guess I'll have to experiment and see what happens.
Thanks!
