Are 850s large injectors? Cause iam running them on e85 and hardwire 255 pump with stock fpr. Seems to work just fine for me.

Brad (C3l1ca) used the stock FPR making ~600awhp at DB, on e85. (He can chime in with more facts).

Not for E85

my buddy made a point to check the fuel filter says it might be clogged ? but if that was the case wouldn't it not start . it takes a min for it to start like crank for like 15 sec then it starts i can hear the pump in the tank as usual.

Im going to run a meter to see what im getting for voltage for everything up front.. And see if the relocation of the battery had anything to do with it running 4 gage from the bat to starter then 8 for main harness and patched to to the starter

my idcs are 90-105 on gas right now its undriveable on e85 i dont even boost it right now again all fuel and air settings are maxed past 3500 it dose not make a difference what i do for base pressure but run leaner when i turn it down .

Deff change your fuel filter if it's been a while. E-85 is notorious for cleaning out your fuel system and dumping it in your filter

Why increase fuel pressure to 43.5 when you are pushing the limits of your injectors? Why not just get bigger injectors and do it correctly instead of half assing it and taking risks on blowing up your motor that you have probably already spent to much on?

And 880's on a stock FPR is pretty stupid 93gtpeater, you should have bought a AFPR before you spent any money on injectors. I'll bet there is a cloud of black smoke behind your car every time you accelerate it's probably running so damn rich. Please tell me you are running dsmlink or something and are not on a stock ecu considering you don't even have an AFPR.

43.5psi is the factory flow rating and what they baseline fuel pressure should be.
