I was wondering if any IX's here running the fpred with stock cams and e-85? if so, what numbers are you making? Also, is it necessary to get cams with the fpred? if so, why? thanks.

You'll probably just get the typical...."If you want the full potential of the FP Red you need cams." You don't need them to make great power. Especially if you're running E-85. I'm sure you would make another 20-30whp or more depending on how aggressive your tune is and what cams you get. I'll be running FP4Rs with Pump/Meth. I'm just waiting on my tune.
