im planning on running about 800HP with nitrous, what will i need to do to my computer? and what size injectors should i run?

Stock 165 MAF ECM will not support that kind of hp,
Stock 730 MAP ECM is alot better then MAF but I'm not sure what kind of power it will support,
DFI is going to be your best bet

you'll need at least some huge injectors like 60# or something and a serious fuel system to supply it

i have a built 350 4 blot short block and a 400shot of nitrous , i was hoping to keep the computer but i might just go carb,

what intake you planning on running?
if you stay MPFI

thirdgenrallysport

what he said. i dont think a tpi will support 800hp.

My cousin built a 383 running a stock TPI intake, it ran 400hp at the flywheel,
but siad there wouldn't be much chance it getting 500hp out of it,
he knows his stuff, builds sprint car and drag car motors for a living

well what intake can i run??

I'd have to see a dyno sheet AND video to belive that,

who tuned it?

if your 88 and running stock MAF setup, its almost impossible unless your car has terrible drivabilty

What crank, rods and pistons you using? 800 hp will send stock rods through the pan.
