where my boost guage is supposed to reach on full boost, mine gets to where it says x10 on the guage. turbo 2 FC btw.
On a good run uphill in 3rd or 4th mine went to the top of the scale (45) once I had the air filter changed to the HKS induction kit, before that it would get fairly close.
It now goes off the scale due to a few more mods !
