Default Mods?
I've been reading on here alot, and it seems like there are a couple of mods that really make a difference, throttle body bore, and '99+ Intake manifold.

I was wondering if there are instruction on the TB bore, as I have access to a machine shop.
Also, what was the big difference on the '99+ intakes?

I have also read, #19 ford injectors, or #24 ford injectors, which is better?

I already have a free flow exhaust, and CAI on my '94 4.0L 2wd, w/ 3" lift.

Thanks,
J

the intake and tb bore will give you about 15-20 more horse.

The 19#'s are good, the 24#'s just flow way more... But they're only as good as the fuel pump.
