shifts with valve body

Been driving around on 80 economy since I installed my valve body and it shifts perfectly. But today while messing around I set it on 120 race and took off when it went into 3rd and 4th gear under pretty heavy acceleration it felt like it was going to break the transmission loose from the truck. Anyone else have this problem? I'll probably be calling PHP monday to see if I need to get the line presure dropped for it or what. Just trying to see if anyone else has had the same problems

If you've got a shift kit, I don't think you'd want your chip bumping the line pressure. My truck has a shift kit in it, and when I had the Edge in it, bumping it to anything above stock would raise the line pressure to the point it would rattle change in the ashtray...was worried the transmission was going to self-destruct...

I was looking at a PHP Phoenix last night and it said that if you have a VB you will need custom tunes in order for the truck to shift right. Stock or Stock HD should be fine. I would definitely take it easy until you hear back from PHP.

Yeah it's only been on the race mode once since I got it. On daily driver it's perfect they are firmer but not really hard. I'm probably doing injectors soon so I'll probably wait until I get those and have it live tuned and get the line presure adjusted then. Should only be another week or so.
