Trans shift points, pressures

[screagle07]

I have the FU chip installed on my truck and love the way it performs. However, I just had my trans rebuilt locally. I let the builder decide what to put in as he does offer a 3 year warranty. For the rebuild, he installed a new billet triple disc convertor,heavy duty clutches and a trans go shift kit. Normal driving the shifts are a little firm in the higher performance tunes but thats where I get the best mpg. I was wondering if the shift points could be softened a bit or do I need custom tunes for this? Its something I could live with but would rather get this trans to last long enough for me to get a BTS.
