I’ve got a 2010 Escalade that the previous owner had lsa swapped. Before the pulley and retune it would shift fine but after the pulley and retune it won’t do a WOT 1-2 shift. He even had another tuner look at it but couldn’t figure out why. It just hits the rev limiter and falls on its face. Could this be in the tune?

Not sure what automatics came stock with LSA's, but are you able to upload a stock LSA + 6L80 tune in it to see what happens? Or maybe just the tune that was in it before the retune?

Current owner doesn’t know and I’ve reached out to the tuner (John weeks) but no word yet. I know he’s a busy guy.

Finally talked to the tuner yesterday. He stated it’s not a shifting issue but like the engine won’t rev anymore like it’s floating the valves. No way I can grab a data log. SOL on this one. As bad as I want the set up I’m going to have to pass.
