i am looking at getting an ATS turbo for my truck, the guy that has it says it rarely gets over 4lbs boost unless on a steep hill or towing lots of weight, also the pyrometer never goes over 600 degrees, he says the rig gets 15mpg wit ha 700r4, not much power... Is there a way to make the turbo have more boost while driving and towing? If no boost while cruising is the motor making any more power than what i have now, J code 6.2, air cleaner mods, dual exhaust,,,,, thoughts, suggestions, thanks

You can turn the fuel pump up a lot with egts that low. That would also increase boost because it is not a waste gated turbo.

Careful.

Rule of thumb is max boost 10 psi and max EGTs of 1000 or 1100 Degrees with a 6.2 turbo.

Also it depends where the pyrometer is mounted

most guys put them pre turbo, so thats the 1100

post turbo is 900,

id rather have pre turbo, mine came post, but im not changing it.
