2wd 3500 Ext Cab D/A


15.155 @ 89.9MPH Very little track bite. Slipping trans, I had to turn the Tow/Haul mode off at the 1000' mark to bring the Juice down to Level 2 to keep the trans from going into Neutraul.


Hot Juice, 90HP Predator.

Those are quite low numbers for a stack, even with reducing from 120hp to 70hp or what ever the hot juice is on level 2. Being a 2 wheel drive and an extended cab it can't weigh much more the 6500#


If you were able to run both boxes as you stated through the first 1000 feet, the tranny can't be slipping to bad.


When I had the TST Powermax, I could slip the tranny at just about any speed over 45 mph, using the higher settings. (like 9/6)

AFE drop-in replacement, straight pipe, about 80-90* ambient. The trans was only slipping in O.D.


Grill Guard, Running Boards, lots of junk inside. 215/75 tires.

Not really fred. It's a light 2wd regular cab and he does the programming so it's basically custom programming that isn't available to anyone else. The guys like King D and M Tomac are doing it with heavy trucks and products that are available to everyone, both of which make them more respectable.
