Default New tunes, ? about tranny shifting..

Ok guys, i got my new custom 87 performance tunes, and drove about 300 miles over the weekend, went camping. I noticed as i am slowing down, around 40-30 mph, as the truck downshifts, i can feel the truck shudder. It doesn't seem to do it every single time. As long as it's not damaging anything, i am fine with it.. just kinda curious. The tunes are great, more power than i ever had to pass on interstate.. the truck seems to have new life. Love it! Thanks Bill!

i would see if the truck does this in all instances meaning...

coasting down hill
letting off gng up hill
down shifting on flat ground

...and maybe engine load?, my truck shutters a bit w the canned tunes but rarely, i dont think its nothin to worry abt. id email or call bill to see what he says. peace

As long as it doesn't happen when your driving with it programmed back to stock it is a tuning issue. All you have to do is tell Bill and he can fix it up for you.

Well, in the spirit of being thorough, i recently ran my tank dry and filled up with 93 octane. I uploaded the new custom 93 tune, and the shifting situation i had with the 87 octane has vanished..plus the 93 octane is even more fun to drive (which i didn't think was possible) than the 87 octane...

love these new tunes!! Bill rocks!

That's strange?
Does it in one tune and not the other?
I'll post it in Bill's area just to make him aware of it.
Peace!

Yeah, it's kinda weird. Just in the one 87 perf. tune. It seems to happen when i am slowing down on level ground.. not really any other time that i can tell.
