Newbie Tuner ?

I am running the 250 tune with egr and dpf delete on a Sparten Tuner. I use this truck for feeding cattle and occasionally pulling a trailer. I am not after really hot rod stuff, but I want the best fuel economy I can get. I have seen you guys post that the hotter the tune the better the fuel econ. Now my question, if I am pulling something or go to pass someone on the road, it has so much power the turbo is hitting 40 psi according to stock dash gauge. Should I worry about that? I am not driving heavy footed, I drive it like I want it to last. Just concerned about blowing the turbo. Thanks for your comments

Many people will say that these trucks will handle 40-42 lbs of boost all day. I'm not convinced yet... I've been conservative and run my Defuel at 32 lbs boost. Also, you're more likely to stretch the head bolts before blowing a turbo due to boost.

he's right the head bolts would come wayyyyyy before you would hurt the turbo.. the whole idea is the power/boost is there "if" and "when" you need it... passing someone you shouldn't be at 40lbs longer then what 4-6 seconds.. it's not going to hurt you.. it's the guys that go from light to light smoking people out.. who are at max boost all the time.. my thing is too much of a good thing....always becomes bad... maintenance your truck...drive with some sense and you'll be fine

just curious if anyone that pushes 40+ psi boost if the stock gauge pegs at 40 or if it will go past evenly like it would if there was more numbers like 50 or 60 psi marking.

I blew a HG towing my trailer over Mount Eagle TN. Looking back I "think" I may have been on a tuner level other than" stock". My advice would be to tow only on stock tune. Or you might learn a $5700 lesson.
