5.3l Chevy Tahoe No Guts on STEEP Pull...

How many miles on the truck? Could a catalytic converter be getting ready to go and when it got real hot it was tightening up the exhaust?

134,000 miles. That wouldn’t explain how I can drive it 16 hours straight with no issues.
 
i'd be inclined to blame torque management- has the road perhaps rutted up worse lately where you have to take it slower now than you used to?

my buddy has an 09 suburban 5.3 & 6 speed that I have to put the pedal through the floor to get it to move up the boat ramp the first time i drove it at the boat ramp it, it was an uncomfortable amount of throttle travel before it would move . granted its a heavy boat, but there is noticeably less power in the newer rig & 6 speed than there was with an older truck with 5.3 & 4 speed,

Oh yeah man, the road is pure shit and I’m crawling up a steep grade. But how do I fix or solve the issue?

Low range. But that means you'll have to see if it's possible to swap the t-case with one from a truck and get the controls working. Or cable shifter.
Or just buy a truck with low range.



It's more than likely the torque management. Unless you're coming up on 3000+ rpm you're way under the power. Smooth road, more speed, you had more rpm and were into the power curve.


GM is driving me nuts. They make the traverse for soccer mom's, they could leave the Tahoe as an enclosed truck.

Yeah, you need to turn something off, it's trying to keep you from breaking axle or drive shafts
my 01 4runner would pull all power unless I got all the right buttons, then it was a crawling mfer

hopefully there's a built ib way to do it and you don't need a programmer

I have a truck that pulls that well, just not as comfy for the 8 hour ride with the family. No idea why there is no 4-lo in this Tahoe. Absolutely stupid.

I’m tired of everything turning into a mom-mobile. I mean damn, some people actually use these vehicles to do more than run kids around and haul groceries!

I’ll text the dude that does my tunes and see if he can do something with that using HP tuners.
 
My 2012 Ram's traction control sucks ass, it won't allow me to spin the tires in 4x4. In sand it just slowly digs holes while not moving forward. Pulling the ABS fuse disables all torque management as well as the anti lock brakes. You could pull the appropriate fuse(s) and pull the same grade to confirm it's a tuning thing.

Torque management is in the ECM. Can be turned off with HP tuner or EFI live.

​​​​​​No fuses, unless you don't want it to run at all.

Sorry, but pulling the ABS fuse will fool the ECM on quite a few vehicles. When I pull mine it disables antilock brakes, traction control and the stability control bullshit, I do get a CEL but it runs just fine. I don't do unless I'm spending time in the sand because I pay for my own parts, tires and diesel, not to mention the 68RFE is a POS:mad3:

On lower budget films the stunt crew will rent cars for filming and we bypass that shit all the time. It has gotten harder or impossible on the newest models but I know from experience it works on more vehicles than you would think.

Torque management isn't traction control. It has nothing to do with the abs. It's built into the ECM and pulls timing and fuel when it sees something that could be considered abusive to the drivetrain. It's looking at engine vs transmission input and output speeds. It can be activated by the traction system, but it's still active without it also.

I may be phrasing it wrong but, pulling the fuse turns my truck into a tire roasting drifting machine in the dirt. The ecm does not limit power to the ground when abs is disabled in my truck. With the fuse in place, a washboard road on a grade is problematic. Last year I was stuck backed in a wet paved parking spot that was sloped, front driveshaft was out at the time so no 4x4. I pulled the fuse and was able to drive out without excessive wheel spin.

I am tuned and have no intention of turning off traction control full time. Tires cost too much

You're comparing a Dodge to a Chevy. Fuck dude, give it a rest. Dodge uses over-active traction control. That's not torque management.
