So lets see:

You could have short shifted at the drag strip and never seen 8 Psi or you could have forgotten to calibrate the boost guage before using it at either location and thats what probably happened.

Verified boost from the Dyno is 7.7 Psi,from AA dyno 7.7 Psi and 7.9 Psi .
and since you are running the same kit 7.5 Psi that you were given is a gift


If your talking about my first dyno i did not know where to tap for the boost log and i assumed that my boost gauge was reading properly. It wasn't so i said what it read that day. I knew i was heading over to Maximum Psi the next day so i would have a boost log so i didn't worry too much.
my gauge is off still i will be getting a new set of gauges in and i will get my boost gauge fixed as well. i have been reading the gauge number with what it read on the day of my boost log so i have accurate number. I havn't lied if you go on and read my dyno graphs are similar to the one from Maximum psi. The only thing its not a dj and Mike stated they read about 30-40 whp lower so it makes total sense.If you read from the boost log you can see i didn't get close to 7.5 close.
