Hello all, I was wondering if there is anything special that needs to be done to tune the fuel pump module in a 5th gen (2014) Camaro SS? I have swapped a CTSV fuel bucket in it with twin dw300's and the fscm has all of the zl1 values in it.
The car idles at 50psi, and ramping up under moderate load it will go up to 58 psi and then after about 5200 rpm it drops to around 50 PSI.
The car is a stock ls3, GPI stage 2 cam, and an LSA BLOWER swap. It is making about 8-9 lbs of boost and has TRUE 85% ethanol in the tank. I even put a couple of gallons of 93 to reduce ethanol content down to about 60% to see if fuel pressure would change, but it did not.
It's a stock LSA blower, 2.55 pulley and I highly doubt the car is making higher than 700 hp. These dual dw300c modules have been in other cars making similar power without an issue on e85. Not sure if i am having an issue with the module or if the pumps are indeed running out.
