upgraded to csp5 from previous single tune.

did the csp5 upgrade from a previous single tune the truck had and now the throttle response is sluggish and slow. and the trans shifts weird now. no check engine light on or dtcs. I am wondering if one of the limiters is being the problem child

When you convert a single tune to a CSP5 OS the original tune ends up in Slot 5. The first 4 slots are stock.

I did the other 4 tunes as well and increase level 5 left level 1 as stock and all 5 tunes have slow throttle response. takes a while to build speed

Then you did something wrong along the way.

I'd backup and convert your original single tune to the custom OS CSP5. Flash that tune into the truck and then select Tune 5 then take it for a drive to confirm everything from that point is good. If all is well then progress 1 tune at a time and test.
