I would like to know if this is normal. My supra in 1st gear, 2nd gear and 3rd gear is boosting 4psi only and in 4th gear and 5th gear is boosting 6.5 psi.

Thats not really normal to do it in more then 1st gear. I assume your car is stock? If so you might want to check for clogged cats especially the 1st one, an upgrade downpipe may greatly reduce what your speaking of.
