I had someone remove vats from my ecm for my swap and change the transmission shift points. The shifts are way to close together and soft, does anyone have a stock map for a 2004 chevrolet lm7 5.3?

Here is a 2004 file. Minor things could be different between yours and this one, like tire size and rear end gear ratio's.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
