high egt's what to do???

I have a E99 that all stock, I put a cat delete pipe on the stock exhaust and have a TS 6 pos chip which I run on the 75hp tow setting. I hauled 14k yesterday and struggled to keep it under 1200. I hit up to 1400 during hill climbs while having my foot on the floor. I get 21 psi & up to 23 psi in the upper rpm range at full throttle. gotta a get this thing cooled down what to do? I was gonna start with a T/B 4" exhaust. what else can I do?

Get more air into the engine. Bigger intake like the 6637.

check for soot around the cac boots and up pipes. No need for the exhaust, since your oem is gutted now.

an intake might help a little but not 100* worth, build a boost leak detector and check for leaks. and like what was previously mentioned check for soot around uppipes.

if your running canned tunes thats gonna be part of the problem

I doubt he has any boost leaks as he is hitting 21-23psi. That's spot on for a stock truck at wot.

Run it on the 30hp tow tune. That 75 tow tune is probably for under 6k pounds.

IIRC, a stock e99 is not rated to pull 14k. Only 10k. Especially going up steep hills. Get rid of the muffler too. Or just get the 4"T/B and a 6637. Together they will help around 150*

FWIW i could hit 20 psi on a completely stock truck with no tunes, hes hitting 21-23 psi pulling a load at wot should be hitting more boost than that with tunes

he did get rid of the muffler, these trucks didnt come with a cat so he used a cat delete pipe to delete the muffler
