So I have a stock GLH-T that came with a boring old Sunpro boost gauge with it. It has been showing boost from 10-12 psi since I got it. I decided to buy a used SRT-4 gauge to spice up the interior a little bit. So once I got it all installed, the new gauge shows a max of 6.
What is stock GLH boost? Could the Sunpro have been inaccurate, or should I go chasing a leak on the SRT-4 gauge now?
