[QUOTE="02SILVERBULLET, post: 10195871, member: 32207"] Currently working on an e85 tune on my truck, 60lb/hr injectors were done at 4700rpm so i went to 80's they are great for the street tune at 13psi. But we tried to make a race tune and the 80's were pettering out at a mere 15psi and 4500rpm so much for 17-18psi. So my question is, is anyone running bigger than 80's on the stock ecu on a truck that would be street driven. my truck is currently my DD. Also I am afraid that the injectors are not the problem at this point but the stock lines, rails and 255 pumps are maybe the restriction. There are alot more guys on the "lrodder" site that are built and run e85, but im banned there. I really dont want to re do the fuel system ever. If I was to buy a set of the new 105lb/hr injectors? Would this help or like I fear is the other parts of the fuel system my issue? BTW, truck is knocking on the door for 600hp and 600 tq at only 13psi and 16* timing (these numbers are approx. I need to go see Dante tonight and get the complete dl as it this was a quick phone discussion [/QUOTE]
