jb4 1st gear boost only 5lbs??
I have been running a jb4 G4, dp's, and dci for a year now. When running logs in third gear I am hitting ~15lbs of boost and the logs look clean. I have noticed though that first gear just didn't seem to have the same kick as the other gears. Well I finally turned on the boost on fuel gauge and noticed that I am only hitting about 5lbs of boost in first gear. The jb4 is set to map 5. I know that there is a boost limiting setting you can set the jb4 to in first gear but I did not set that parameter. Is this a function of map 5 or may this be another issue?

I believe is a setting in the user adjustment software you can change for 1st & 2nd gear. Is there so you get better traction.
I wouldn't recommend putting it to high as you'll be over 1st gear after 20mph.
