What turbo? 7x.011s or 7x.012s are still plenty cool for a street setup with the right turbo

I'm running the same turbo from DAP and they recommended the 7x.010 injectors. Claimed at 150-175 horse injectors. My truck moves out real good thru the whole rpm range. Turbo lights quick and it gooooeeeeesss

7 x.010 as they will give you enough fuel to max that turbo while still being really easy to tune.

I've never even seen my egt's go above 800. And by the time they even get that high I'm well above the speed limit and have to back off. And they're sac

that's good i was worried about the temps.

I'm worried about that gearing...4.56....oof. Even with 37's: 4.56 gearing is gonna be up there in RPM on the freeway in overdrive.

I woulda gone with ~4.10 gearing. get the RPM under 2k @60. You'll have more than enough power to pull longer gearing and make more use of the gearing.

I have 4.10's with 35" tires and I want 3.54 gears with 35" tires... My gearing feels worse than a close ratio 5spd MX bike lol.

i was under the assumption that 4.56 gears with 37's netted a close to stock tire size to gear ratio ??
