4L65E Lazy shifts when into throttle

[1972C10_LS]

Having trouble getting the transmission dialed in. Wanting it to shift firmer and not just slide in and out of gear. It was shifting firm (sometimes 2nd gear scratch) for the first few test drives and ive changed something and it seems lazy now. Iv'e attached my current tune called c10.v1.hpt. I tried making some more extensive changes in the 2nd file c10.v2.hpt attached but it wouldnt even move past an idle in gear, as soon as youd give it any throttle it acted like it disengaged the transmission/torque converter like it hit a rev limiter but without actually revving up, very weird so I reverted back to the c10.v1.hpt tune. Help!

This is a 2007 5.3/4l65e new body Silverado 2wd drivetrain.

In the the first tune it says 4.10's and the second says 4.11's, so what is the gear ratio in the truck?

Also .400 to .475 arent really quick shifts, lowering them to .300 would be alot better.

Oh, theyre 4.11's..What table has the shift speeds youre referring to? Im still learning how to navigate through hp tuners....thanks in advance.

NVM i found the tables. Anything else you see that would help firm up the up shifts?

I will change the 1-2 2-3 tables to .300 and see what it does.
