I have 2009 GMC Denali and i would like to take it to dyno, there is no AWD dyno near me over here, is there any way to disengage the AWD?

 

There is but it's sketchy as I recall. I'll let one of the AWD guys give you the low down.

 

if u do find a way lemme know please. The AWD dynos here are either waaaay too expensive, or the dyno operators never around to run it.. :/

 

Same over here, i talked to one and he said bring your car and when i came i found that he don't know how to operate it, the ABS start flashing on my car then he told me we can't dyno my car and the problem is from the transfer case.

 

Is it that only me who owned a AWD Denali?

Where are you tech guys?
