That is true. I have a good tow program. After adding the DP Tuner the difference is absoluely amazing. I tow mostly in 60T In my case I can drop from 65mph pulling a grade to 60mph and drop egt by 400 degees which keeps me in the safe area.
I have a early 99 with smaller injectors and HPOP, what I read once made alot of sence to me. With stock injector and HPOP you may only benift so much. A 60hp tune would be max for my system.
But all that said. If I was to do some upgrades I would go with bigger uppies, 4" exhaust and maybe a 6.0 intercooler (just because I could pick one up cheap).

Ok up pipes are on turbo response a lot better but still only 28 on boost and can't tow very much with out gettin hot... 28 foot bumper pull camper weighs 8000. I have towd in all chip settings and even stock tune I have to watch it it will get to 1200 and in any other tune it gets hotter way faster. I did a short hard pull and hit 1350 and backed out and that was easy to hit... What do I do... Water meth ?

OK... I'm following now - there was a space between 2 and 8 on your post, and I didn't "put it together".
Your wastegate wasn't adjusted when you installed your 38R - I made the same mistake, and I corrected it. Torque shows my boost with a boost-fooler, the true boost is the top-right gauge.
I also have the S&B intake, a 4" exhaust, and zero boost leaks.

dmanshane... have you tried downshifting a gear when the pyro gets over 1200?
I have found downshifting to instantly reduce EGTs when climbing a grade under load.
Even though the engine is screaming at 2500 RPM, the EGTS drop a lot.

What y2k said. Get it out of overdrive before you hit the grade. Rpms around 2500. If you hit top 1200 egt's (I think my gauge turns to red at 1300). come off the peddle and down shift if need be. I have had to pull a grade or two towing 12,000lbs at 40mph....but not very often...

That's kind of what I was suspecting, but I meant REALLY downshift.
I would try running in 4th or 3rd on the grades, depending on how steep and how heavy the load is. I would aim toward elevating RPMs up to between 2,200 to 2,600, and dropping speed to around 50-55 when towing those grades... and see if the EGT's don't drop substantially (and sustainably).

I'm thinking of getting back to that 28 PSI max on a 38R - I did better than that with a stock turbo.
Boost leaks, sub-par air intake, wastegate adjustment, stock exhaust, hot tune... these are the things that immediately come to mind.
