That would be me
Unfortunately my gauge lost the max boost read when they turned off my car but I've been seeing 12.8 lbs. lately. I figured it was the new software from the dealer when I had my HPFP replaced. When I got home, I found out that the dealer had reversed the solenoid bypass (recommended by Burger) and with it and the JB+ at 100% I was seeing 13.7 lb readings. Sneaky little dealer
So there's gotta be a couple more HP in my car but after seeing Alex450whp pull there is no doubt that I have to get some DPs.
