Buddys truck I tune has 100s, stock cp3 gets around 20ish mpg. No haze getting up the road. Hits 1900 or 2000uS if i remember has a danville 72 and has been 11.86.
I'm pretty sure pay made alot of his big power on Casper with small injectors or even stock. You can still make power with anything boys, up to a certain point. But if your cp3 can hold the pressure, and you have money, it's always best to get the biggest you can. It will be the easiest on hard parts.
FWIW, I thought leaving the CP3 stock would be a good "failsafe" of sorts running 60's on the factory built LBZ, boy was I wrong....9 days is all I got until a piston cracked :baby:
I have kyle's old 40% overs and with everything set up like it is, it is very clean now. I don't mind them. If I do end up using the motor parts I have in this build I will be going to a larger injector, but still probably no more than 60-80% just because I wouldn't need to push any harder than they would take me. :thumb:
