no its not to early it just feels like its taking a long time. could that be due to the tq managment that you took out? i just drove it around for awile it feels strong! runing good now but the shifts just feel slow its shifting at the right rpms weird but its fine. just slow

Try taking the trans settings off the old file and comparing them. Like line pressure, shift time, etc

Wonder how many trucks Wheatley works on daily...
