by getting bigger injectors and keeping the stock turbo, you will see an increase in egt's!!! more fuel, you need more air!!!

if your wanting your stock turbo and keep your egts down, i would go with the 90s. im running the 5x.014s and i can hit 2100 with the stock turbo on mine, but DD i am running the stock fuel plate to keep my egts down and stays below 1250. my mods are in my sig. i laid down 433 and 1156 last weekend with them.

Thats just not gonna happen, When I hook to a sled my pyro (1600*)is burried within the first 75 ft. Thats why I unhooked it

there are some mods you can do to your stock turbo to help keep the egt's down

Also you dont need injectors to have a good pullin truck with 350hp. Sledpullin on the other hand might be different. But with daily driving and pulling trailers; gov. springs, intake, exhuast, tuning the pump and bumping up the timing will be a stout pulling truck as long as your clutch or tranny will hold it. All this shouldnt be done with out gauges first.

Also fill out your sig so we know what you have
