I'm definitely going t-trim. What type of fuel pump/injectors does everyone usually go with?

I'm using the z06 pump with a KB boost a pump and 83# injectors. Otherwise stock fuel system. I'm thinking the pump will max out in the high 600s on the dyno with e85. Injectors should be good for a bit more than that, probably high 700s. I can let you know for sure after my dyno results, I'm planning around 650-670whp, hoping the pump keeps up.

Sure, will keep in touch after my tune. Just running the base ECS kit on a built 427 LS3, only expecting 5psi, might take out restrictor plate for an extra couple pounds if I'm not pushing the fuel system with 5psi. It's my daily driver but one or two autocrosses and maybe HPDE per year.

For 700rwhp do the T-trim. The si can do it but will pretty much be tapped out.
I would do dual pumps or add an external pump for e-85. Then again z06 pump with a boost-a-pump/etc should squeak out 700hp.

Thanks for your interest in our kit. You can order a T-Trim "tuner kit" that would come with everything except injectors and a boost-a-pump. You could also run our high capacity fuel system, and then source your own injectors.
Here's our fuel system:

Got the tune pretty much done, but couldn't get dyno time for some final WOT adjustments. The kit made 5.5psi around 4500rpms and held there until redline. I imagine I'd see about 7psi without the restrictor plate.
Fuel pump kept up great, so when I'm on the dyno in a few weeks I may take out the restrictor and see if it can maintain pressure at higher power levels.

Yes, E85 and 80# injectors with Z06 pump and boost a pump, otherwise stock fuel system. Car is making 640rwhp and zero loss of fuel pressure. Later this summer I plan to push it a little further to see how close to 700rwhp I can get without pressure loss.
I may try the new Walbro 450 which flows about 10% more than the Walbro 400 at 60psi. Should be good for at least 750rwhp.
