So I splurged on a couple credits for my HP tuners. Once all said and done, I can change the E92 ecu and the t87 tcm. Have several friends that have the same drivetrain combo and they have the same complaint, rpm's to low around town (1000 rpm@30mph). Changed the part throttle shift schedule to now where rpm's are in the 1500-1900 range around 30-40mph. Much happier.
