Has everyone come to a consensus yet as to what injectors are needed on a RXP 215 HP with stock fuel pump and X-charger (with external IC and aftermarket air intake as well) ??

38's and RRFPR. Running good for me. I dont have my WB yet though. I keep checking my j-pipe bell for good measure. Still flawless at the present.

I'm wondering without the RRFPR though..

i do know one thing my stage 3 boat outlasts the stock PX my buddy has by a few bars of fuel consistantly.

You would need 42's to run at approx 255 hp with the stock fuel pump & 58 psi of rail pressure.
