Impressive numbers! 610 is my highest. Stock lmm pump, injectors, turbo and some spray. Stock dmax defenantly has the fuel for some impressive numbers, just needs more air!

My #7 had EFI dsp5 by EPR a fass 150, mbrp 4" Exhaust, PPE Valve, and stock intake and made 548hp on Industrials Dyno and 549hp on Hallers Dyno, 547 on Custom Auto's Dyno. Since then I have added ported turbo inlet pipe, Diamond Eye Down Pipe and AFE Stage ll intake. I am curious to see if I gained anything. I know my tune #2 made 542hp and held rail. My big tune drained the rail down to 18k but still put good #'s down. A set of twins and a dual C would sure help out!:D

You can be my stock turbo idol lol

Im hoping for around 550 but we will see. Ill post when I get the truck complete.

Seems like some people have laid down alot bigger numbers than I was expecting with stock pumps.

Whats the cheapest way to get a good dual fueler setup? minus the pump?

You prolly wont hit 550 on the stock IHI turbo unless you spray it. At even that I wouldn't do. You'll see 500-530 if your CP3 is healthy. But every dyno is different.

That would be the cheapest. Then buy a good used pump. Personally I would run what you got. Max effort tune and see where it takes you. Anything around 500hp is a blast to drive. Often wish I would have stayed at "stock" levels instead of twin-everything-money-pit haha.

I know the LLY is a bit different but I made 576 on fuel and 614 on spray with a stock LLY pump. My buddy James' LB7 made 540 on a stock IHI, cp3, and sticks.

Yep.... It will sound rough at idle.... The rail pressure will be quite high. But it will start and run

My LLY pump with LBZ regulator ran smoother than expected. I drove it a few weeks before having retuned. Usually only noticed a minor lope as I was coming to a stop. I have heard of other people with more noticeable differences though.
