26GT got boost - not ESS/Whipple/Procharger *Roush 2650 Phase2 810hp*

I am running the stage 2 kit. My tuner informed me I did not need the booster unless I go with a smaller pulley. The 3.6 or 3.5; then I need to address the fuel. I am running the 3.75, and it's fine.

Some tuners are fine with a bit of pressure droop from the low side but not me. It’s fine on basically new cars, but as the pump ages it can get worse. I wouldn’t chance it for the $400 shipped it was. Easy tune update and now my low side is rock steady.
