2015 Chevrolet Silverado 2500hd W/T 6.0l 6l90e 119,****** miles. I’ve owned this truck right at 2 months and have a intermittent acceleration issue very noticeable around 3000rpm it feels as if the ecm is retarding ignition timing. Wondering if anyone is having the same issue. no check engine light on

So I just purchased a 2015 2500hd 6.0 6l90 4x4 113,kkk miles and I’m experiencing this exact issue for the past 2 months I have been researching this exact issue and this is the only thread I have found thus far. 3000 rpm feels like hitting a wall and it doesn’t do it all of the time. Did you find a resolution to this issue. A lot have recommended black bear performance tune, I’ve heard that can help with drive ability.

Did you ever find a solution for this issue, im experiencing something similar.

im experiencing this issue as well, any update?

Any update on this? I recently purchased a 2015 2500hd 4x4 6.0 and In 2nd 3rd & 4th it feels like the TCC engages at 3k rpm and there is a sudden hesitation until about 4k rpm’s and it seems to wake up and haul ass after that
