boost pressure question
 

hi all,
i was doing some pulls and found out something weird. 2nd gear pull it would max out at 7.4psi, 9.3psi in 3rd and 10.9psi in 4th. i got these reading on the rtek7 2.1, and it show on the boost gauge as well. Is it suppose to be like that or even through out the gears, peak boost around 5200rpm. Running mild ported s4 with stock turbo and custom exhaust.

Here's an old thread:
