i have 2 questions about something that's been going on with my SR lately.

1. I noticed on my Greddy boost controller, when i first floor the gas, the PSI goes kinda high (like 10-11psi), but then about a second later (while i still have full throttle) its drops down evens out at about 6.5-7.9psi. I though it's supposed 2 stay at high psi because the setting i put on it is for 12.5psi, not drop back down to high 7psi. Is that normal or what's going on??

and 2. I was on the highway, with the gas on full throttle, and it would sometimes bog every now and then for some reason for about a second. Basically, when it's spooling at full throttle, it will sometimes bog itself. What going on with that?

I know it's a lot of reading, but Im just trying to make it as clear as possible. Hellp!! thanks.
