Alright as some of you know I got the Dave H intake in the fall last year. I made a few runs in late fall last year. Then parked it for the winter, I never got around to hooking my boost gauge back up until this last weekend. I have a 14.5 psi wastegate spring governing boost. I can only make about 12 psi boost max though. Prior to the intake install I would boost to 14.5 all the time no problem. The only thing different now is the intake (which must have a considerable increase in volume over stock), and I also changed out the cool side I/C piping from 2.75 to 3.5 inch from I/C to the throttle body. I've also switched to the Q45 throttle body but that shouldn't affect anything. SO does the increase volume of the intake and the I/C piping affect the boost pressure? I do have a 17.5 wastegate spring I was going to install here shortly, so I'll see if the pressure goes up with that spring installed...Anyone have any input?
