an air filter will drop your egt's a few hundred. what size DV's are you running? the factory turbo is good to around 350 HP.

 

Thanks, air filter just moved to the top of my list then. My DV's are stock, which I believe are 181s

300 to 350 hp is more than enough outa this truck and that's where my eventual goal is set i am just hoping a good single disc TC with a lower stall will handle the power reliably
I know they say they are good up too 500 but I wonder
