I usually over boost my target by a little on the other tunes. this one had me thinking something was wrong at first until I swapped to old tune and it boosted like normal. it usually hits a little over target then settles within a couple tenths. this next update can you put my latest version of e30 with the map switching capabilities? I believe it was v4 thank you. can't wait till next revision. I was hitting 21.6 psi with no issues before. thank you, Jason james
