2500HD w 8.1/Allison Opinions
Looking at updating my current tow vehicle by a couple of years and 100000 miles. Would like valid opinions on the 8.1/Allison combination regarding towing and overall durability/longevity. Don't care...

Just feed her lots of gasoline and she'll run forever. 250K on my 02 and the tranny still shifts like it were new. Just put a new water pump on her at 250K. Did I mention that my 2002 has been supercharged since 5k miles? Love this truck.
Which charger did you install? What power/torque ratings before after did you see? Any mods to the engine along with the SG?
Installed the Whipple kit with Intercooler. Not sure of the exact HP/TQ ratings as that was 11 years ago. But it ran like a scalded ape after the install. The intercooler sprung a leak (Water to Air) about 75k miles ago and I couldn't find a replacement so we made a straight pipe and installed it in place of the intercooler. Whipple has a nice kit. Looks factory.
