What is the 2006 stock hp/trq limit of the 48re tranny? I'll be receiving my Quadzilla box (0-30-60-100hp) and Commander tomorrow and would like to know whether or not I can periodically run on that highest setting safely as long as I'm not towing or have a massive load and I'm not beating the crap outta my truck by hotdogging it around all the time.

I've read somewhere else the the '06 48re could handle 450hp without the need to upgrade things like the VB and TC. Whadaya's think?

 

about 75horse over stock is all it will take before you start slipping. you can run to the 100 horse for a little and it wont hurt much since I believe the quad box senses tranny slip and will defuel to protect it.

run that bad boy on the 30 horse setting and you will be amazed how much it wakes up the engine
