    Sorry for hijacking your thread @dustinbrock. It sounds like your engine is running within spec.

    Like one of the post stated, elevation will affect the pyro temp also.

    I used to touch 1100°f on stock mxs set at 475 but after BD tune I run 700° to 900° f same max 40psi boost.

    I pulled 108k load the other day and I was watching mine. I run the rolling hills in Wyoming/Colorado and I rarely see it hit 850*. That's with 24.5" talls and 3.36gearing.

    Ok guys. I have been trying to figure mine out. 475 bxs 336 rears and a 10 speed. Pyro is post turbo that I installed on the truck. Flat ground and 63mph temps are 830. I have seen it get high as 1050 in a good strain and a hot day. I never have seen the truck build boost over 35. That's the most it will do. I have visually looked at everything under the hood. Do I need to take it to someone and see if I have a air to air problem or do I just need to turn it up?

    Are you saying that you are 950* post turbo on the compound set?

    If you look @ performance spec on TMI, the temp varies with exhaust flows. @1200 rpm it is about 300 degree drop. @ 2100 rpm it is about a 400 degree drop @ turbo outlet.
