625 was fine. Hit the streets in the industrial park and it sucked. Just about got stuck in 4wd with the diff locked at a stop sign.

Went from 460hp to probably about 525ish
What HP was yours from the factory?
Same here not a powerhouse but deff a noticable gain. Went from dropping a full gear on the hills to just splitting to 8L. Most of the hills around here besides a few we never move the stick on both trucksLast edited: Dec 8, 2021

My understanding is that they're advancing the timing to gain the power and efficiency while maintaining emissions compliance by fueling based off of MAP sensor readings.
I've always enjoyed the results of bumping timing on mechanical diesels so I expect somewhat similar results. They sound much better with some timing in them!Flint1, singlescrewshaker, Tug Toy and 9 others Thank this. -
Most common is the position sensor in the transfer case actuator. There is lots of documentation and a bullitens. The actuator itself can be removed and disasmbled and a new position sensor installed. Or install a rebuilt actuator. Sensor last time I did one was only 60$ cheaper for the sensor then a new actuator.
Those transfer cases have big issues. Its a 246 autotrac.
The bearing for the pressure plate can fail. To diagnose that drain the fluid and see how many parts fall out.
The oil pump is held into the case by a very small clip. If that it breaks ( and it does) the pump will rattle and wear a hole thru the case, about 4" ahead of the rear seal.
There is a case saver you can buy to repair that.
Either way, change the oil, use the blue autotrac fluid from gm.
I never liked the auto function, its either slick enough for 4wd or it isn't.
Attached is a net pic of the stock pump retainer and case saver.

I'm actually ashamed of this. Glad I didn't do it, but I still have to take it. -
