Yeah, stock tires. Is your tune setup for your larger tires?

 

As far as i know it is setup for the 34.5" tires im running, my truck with stock engine and tune and the shitty tight *** converter that was in the mad dog even after the tune would shift at 45-50 and closer to 5300rpm wot or even just getting on it, as soon as i put the tb converter in its started this early shifting crap, im wondering if it doesnt have to do with the higher stall converter..... Im going to change it this evening when i get home to 38 to start with and see what it does.... If i was to go off of the yukon's factory tune, 1st to 2nd is 40, 2nd To,3rd 112, 4th was 278 or some ridiculous maxed out crap, thing i noticed with it is when i take off from a light with the shifter in d it will hit 40 and kinda hang until the rpms catch up, but if i pull it into 1st and go wot, she will pull to 53 at something like 5800rpm and then i have to shift.... After that the yukon just kinda hangs at 53 and will bounce off rev limiter quickly!!! Just comparing the same trans (for most part)in two different vehicles trying to rationalize it!!!

 

Also noticed tuesday when i swapped the trans my engine mounts are about done, guess this new higher hp engine did them in they were fine before now theyre starting to seaparte guess ill be replacing them when i swap my headers in.... Damnit!!! It never ends!!!

 

Anything else yall see out of sorts with my tune, aside from fact its for the old cam??
