I did did a cam swap in my car and put a higher stall converter in my 4L60e that is in a 2002 Camaro with 52k miles now when I go to do a pull the transmission does not shift and it hits the limiter I have not messed with the trans tune what so ever. Any ideas on what it could be?

You did not log most of the pertinent transmission PIDs so it is hard to tell precisely what is going on but it seems to be shifting as long as you don't give it too much throttle. 1-2-3 for sure, maybe 4th I can't say with so few PIDs to work with. Although in theory it should not affect shift points much, I would fix the MAF reading to start with, it is so far off the load calculation has to be totally wrong. You did not log that either but looking the fuel trim and the very high reading at idle it is obvious this tune is not setup right. Once you get that dialed in (not something I can help with but I am sure if you aske on the appropriate engine forum someone will be able to help) if it still does not shift under heavy thrtoe, take a log with all the transmsision PIDs and I should be able to help.
