Do I need a T-Rex for a Procharger P1SC?

Code Red · August 1st, 2006, 01:35 PM

I just bought a used P1SC for a '95 GT. The original kit comes with a inline fuel pump which was not in my kit.

I already installed a in-tank Walbro 255lp fuel pump. Do I still need a inline pump?

I resently installed 30# injector and 30# Draw thru MAF. However, the kit I bought came with a 42# blow-Thru MAF.

Should I:
1. install 42# injectors - or,
2. get the 42# Blow thru MAF recal to 30# - or
3. leave the it as is and have the tuner tune for a 30# Draw thru MAF?

youwill not need the inline pump. ut would be wise to change up to he 42#, but the 30# might be able to take it. what kind of boost should you be making?

the supplied inline pump most likely flows less than your 255 lph intank so it would probably be a hinderance

i thought you need an inline to keep up with the volume needs of the boost. I have a 255 lph in tank pump and have a t-rex inline sitting in the box that I was going to install. Im going to be running about 8 lbs of boost with 42 lb injectors and no fmu .
