you guys know that the stock fuel pressure is 55PSI right? if your running the stock PCM you will need to have the injector timing modified to match with a lower pressure pump. otherwise you are going to starve to motor of fuel. I am going to be using the stock pump out of the 04 ram in my car. because i already have it. (its in my doner truck) it will need to modded a little to fit in the stock tank, but its possable. that pump will support a good ammount of power as my motor has a big cam P&P heads, long tubes, a 150 shot of nitrous, and all the other bolt on goodies.all being driven off of a stock pump. so i can see it being just fine. its just an option i wanted to toss out there to you all.
