Upgrading to 11lb pulley....

Current setup is: 1998 Cobra, 600b, 6lb pulley seeing about 4lbs (high altitude), stock fuel pump, stock injectors, fmu (not sure if it's working because fp never spikes), and no chip or tune. It has been running fine, no detonation, though not a huge amount of power with the low boost.

I have the following parts ready to go on: 30lb injectors, 80mm MAF for the calibrated for the 30lb injectors, ATI inline pump, and a 9 and 11 lb pulley.

I suppose I'll need to get it tuned afterward and a chip....any recommendations on what chip to buy, and am I missing anything else? Also, do I have to remove the check valve in the intank pump before fuel pressure will go up?

Thanks, Al
