Ok, I don't know much about upgrading the fuel system. I just wanna do a good job for not too much $. I have a straight through exhaust, intake, m2 medium ic, power fc set for 14.7 lbs. Can I get away with just adding a pump w/o injectors. Which pump is better rp or denso. Rp is rated at 1000 hp and denso 500-i have neither 1000 or 500 so I don't know if that matters. I heard the rp can be loud. is one easier to install than the other? please let me know. thanks
