In first gear, I rev it to 5K and by the time I look at the gauge, it reads maybe 7 psi.By the time I'm in second gear, its at 0 psi and its got to start building boost all over again. But once I see 3k rpm its starting to build and by 3700 its at 10 psi and climbing fast to 20-25 psi but once again, in the higher rpms, its to small and over spooling. From second to third gear, theres maybe a 10 psi drop and is really pulling hard till it chocks out.Oh well, it is what it is. Even with NOS, its still has all the fuel I would ever need.I'm looking for a VNT1756VB or a GTB VNT turbo.

up in tire smoke?

enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..
Even aside from the tire/transmission problem, you're already at 5000rpm and full boost in 2nd and 3rd gear. Not sure what PBS's governor spring is doing exactly, but in that 1/10s, you could hit some pretty high rev's, and that's not even taking into account what would happen in a missed shift...
