Default Finding More From the VE

So i am at the point where i want to find every bit of power my ve pump on my 93 can produce and i need your guys help! heres a list of what ive already got done:
-Bosch 4200rpm gov spring
-Denny T stage 2 Fuel Pin
-Fuel Screw close to runaway
-AFC lever grinded
-Starwheel bottomed out
-Heavier 89-early 91 style fuel pin afc spring
-Smoke screw bottomed
-Speed screw/WOT stop removed
-Advanced timing a little more then 1/8 inch
-about to reclock the throtle shaft index 1 tooth and grind lever to adjust idle
what else can i do to this pump this is about all the info i can find and the truck runs pretty good w this but im trying to make serious p pump contending power numbers with a ve but still keep it streetable i dont want to spent $2500 on a non streetable 14mm id like to here some reviews about the streetability/longevity of a 13mm but id like to stay 12mm. I understand that i still need to play with the tuning of my afc to get everything dialed in just right but i need all i can get out of this pump, any help is greatly appreciated!

you say you want to get your afc dialed in... you arent going to do that with the afc lever ground and your smoke screw buried. also you probably can do more than 1/8" timing, like 3/16-1/4".

what size injectors are you going to run? the factory intercooled injectors are pretty tiny and won't make anywhere near a modified ppump power.

If it helps i had m&h make me a dual inlet manifold and y pipe for mine! helped egts and cleaned up the smoke. mine is non intercooled and the fuel screw is in some and afc down with a pin and it has all the power you could use for pulling. (and i pull a 12000 lb toyhauler) I need to figure out how to post pics but they did a graet job at m&h! and it was cheap!

youre going to need quite a bit then. injectors like 6x.016/5x.018 or in that area, at a minimum 1 tooth advanced on the pump timing with a timing spacer, ported head with o-rings, a big intercooler and piping, and probably an s300 like a 62/65/14 instead of the hx35... or a big shot of No2 with a big external gate.

what are you going to do for a transmission?

What he said. 5x14s will not be getting all you can out of your pump.

Sent with a Droid RAZR in one hand and 14,000 volts in the other.

any injectors bigger then 5x14 will be too smokey on the top turbo, nick lusk from lowbudgetdiesel is my man and he knows his stuff 6 hole spray patterns are stupid on 12v the fuel hits the side of the cylinder wall not the bowl like it should 6 holes are for 24vs
