Hello,

I've got a 17 GT with a Stage 2 D1X ProCharger and 4.88" pulley. I've had the kit for 2 years and haven't had an actual boost gauge installed. I initially unlocked the vacuum reading on the dash with FORScan to include boost. I've heard from many people that this reading is inaccurate because it's inferred.

I finally decided to install a dedicated boost gauge, but I'm seeing only up to 3psi. Through use of smoke method, I've not located any boost leaks. I've been unable to locate any article, forum, FP post, etc that indicates what the expected boost reading is for this setup. Any help is appreciated. Full engine mod list below if it's of any help.
