Jaymz Posted January 17, 2009 Report Share Posted January 17, 2009 just remove the front drive shaft... after the dyno do NOT use the brakes to slow... or kiss your t-case good bye... let the truck slow itself and you'll be fine. I've dynoed mine over 20 times this way, no issues Quote Link to comment Share on other sites More sharing options...
DAVECS2 Posted January 17, 2009 Report Share Posted January 17, 2009 We have had several problems with this over at the Denali site. The truck drives fine but when they get in inclement weather they realize that the viscuos coupling is not transmitting full power to the fronts when need be. I would not dyno on a two wheel dyno. In fact I have not and I have a blower and a host of other mods. Quote Link to comment Share on other sites More sharing options...
ss04Flores Posted January 20, 2009 Report Share Posted January 20, 2009 if you pop your hood on the right bottom side of the engine compartment it clearly says not to use a 2wd dyno.....must be a reason for that. when my truck gets tuned they tune it the old school way...on the streets. takes longer but i dont want to risk it.
