i just put a stroker in the car and it runs very lean. i have a 255 lph fuel pump, bbk hi flow rails and 30 lb injectors, also a c&l with the correct tube for the injectors. the throtle body is 75mm. we have not adjusted the pressure reg. yet. any advise is greatful. thanks.

 

I would definitely recommend adjusting the fuel pressure if you know you're running lean and ESPECIALLY since you haven't adjusted it yet.
