Any injectors bigger than stock will raise egt. Why would you want injectors, are yours bad or is it for more power, if for more power then do the turbo before the injectors. Heck a stock turbo will not hold up to stock injectors if the truck is chipped and ran hard. My second stock turbo lasted less than 3 years with my stock injectors. I was kinda bad about letting it get over 30 psi boost too often though.

Ok please tell me how adding JUST a turbo you will gain anything . Stocker will work with 1s and decent tunes .If the OP is after alot of power then yes a turbo will be needed but the way the reply was written it makes it sound as if just bolting a turbo on will give you x amount of horsepower.

Any upgraded injectors will fry the stock turbo, eventually.

Run the truck hard and over 30 psi often and yes it will be garbage. Not many people go with bigger injectors without future plans of a bigger turbo

Looking for 05-07 front end with Harley Lights

OBS and SD turbo's are very different. 1.15 vs. .84 turbine housing.

Stage 1's will be fine in a SD turbo. Stage 2's can get dicey. Stage 3's, you are as stupid as I am.

It all depends on how you take care of your truck as watch your gauges.

My official position is that stage 2 is the max injector for a stock SD turbo. And that is if you move to a ported compressor housing and a 1.0 or 1.15 (van) turbine housing. With proper tuning, that is a towing BEAST.

No need to be an ***

If you baby the truck it will be fine, if you constantly run the truck over 30 psi, you'll end up frying the stock turbo.


But its different between an OBS and Super Duty. They have different sized turbine housings.


If you don't run your truck hard, stage 1's will work fine, stage 2's will if you have upgraded parts on the stock turbo. But if your constantly pushing over 30psi, the stock turbo just won't last.
