Should I use a T-Rex or not?

PearlWhiteGT · 07-17-2007, 12:36 PM

I bought a used S-Trim for my pretty much stock 306 with 15K miles but it didn't come with a T-Rex or FMU. I'm going to run a PMAS 80mm & some 42lb injectors. I have a 255 intank fuel pump so my question is do I need to run a T-Rex or will I be o.k. with out one? What do you think would be the best way to go? Only plan on running about 10 psi & plan on having it tuned.

I would install a T-rex or some type of inline pump to help your 255 lph. I would not use an FMU, with your 42 lb inj and a 255 pump with an inline you should be good for around 600 hp at the flywheel.
