Default Towing EGT's

I bought a Gearbox Toyhauler model 375's 5th wheel. Its 38' long. I loaded it up last weekend and towed from Bakersfield, Ca. to Las Vegas. I hit the Tehachapi grade on Hwy 58 and the Baker Grade on Hwy 15. Both are long 6-7% grades. My trailer weight is around 14,000. I kept EGT's at 1200 or lower but after a while on those big grades and had to shift down to 2nd gear. I have the 80hp tow and 60 hp tow from DP Tuner. I am sending it off to get his 40 hp and 20hp tow tunes added. Would a 1.00 housing make the egt any better? I have bellowed up pipes and the turbo or innercooler does not have leaks. I ended up pulling both of those grades at 40 mph. Truck does decent on flat ground in overdrive but on the big grades I thought it would do better.

Any tuning?
That, and a different turbo, would go a long ways toward making your setup work.

I used to keep my egts below 1350. Never had an issue. But honestly that sounds about right. 40-45mph up hill.

175/30s woke up my 7.3 where it would pull the same hill at 50-55.

I would sell off the D66 and go T4 with the SXE or KC turbos SXE style drop in. The D66 has not had the greatest reputation. However see if the Hydra and new tunes help.

Youíre going to have to watch them. Itís a tuned 7.3. Itís going to get hot on long grades.

I have a similar setup, some differences. These are old trucks and not nearly as
refined as the newer ones so you can't expect them to pull like them even modified. You
get slowed down on 2% of your miles with what you have and the trip takes a few
minutes longer than if you could keep speed limit. Truck is much better than stock
with the modifications, I just live with it and relax knowing I have 50K more in my
retirement, and pull the long hills a little slower. I can usually keep the speed
with just dropping out of OD, but if it gets slowed down by other traffic I occasionally
have to drop it down to 2nd. I suspect that is what happens to you.

Before being modded I pulled into Death Valley from the west with a large TT, had it
down in 1st for the top half of the hill and had to stop part of the way up for the
transmission to cool down. Coming down that hill was just about as fun for the
brakes.

What kind of boost is it making when pulling those grades?

It will make 15 psi on the flats or slight hill. On the larger grades it makes good boost but I cannot remember exactly. I want to say in the 15-20 psi range. It gets hot when I roll my foot into it. It has pedal left in drive but gets hot so I downshift. Once I down shift I get way our of the throttle and hold it it 2,750 RPMS in 2nd gear. usually around 35-38 mph. I need another gear between 2nd and drive.

Totally agree with you DMD! I just want to be able to hold drive even at 45 mph. I might try a Mishimito Innercooler next then stage 1 injectors.
