Fueling Problem???????????

I need your thoughts, and expertise. You can read my sig. and see whats I have. Heres the Problem.
I was at the NADM races this weekend, in Denton. I really think the truck Should run in the 7.90 in the 1/8th mile. All I can get out of it was 8.26, it only was running a egt of 1200 degrees at the finish line. A friend of mine watching all my passes, said no smoke after a 100ft, from the line. My Smarty TNT-r, was on sw9, rp3, tm2. Rail pressure would max only at 25k, then drop back to 19k and try to recover. it is definatley a fueling problem. What would be you alls suggestion?

Well you hit the nail on the head, if it is dropping to 19k your cp3 isn't cutting it.

Well that just sucks. I was told from II, that the 33 percent over pump would carry those injectors. now I guess I need to put a dual setup on it.

Yes you can keep your modded pump and run duals. You can try an mp8, I would borrow one first. I think since you are draining and not recovering the mp8 may give you a little more time before you drain it, but I don't think it will solve the problem. JMO.

Yeap, draining the rail. You can try another single CP3 from another vendor or go for a duel fueler setup.

Thanks Thomas, I think I will Pickup an MP-8, and run it with a duel pump setup. I knew I should have went with two pumps to begin with, but thought to keep it simple with just one. Now which one is going to be the best? PPE looks like the most popular, and least expensive. Thanks everyone for their input.
