I just got an Cobb AccessPort V3 from Stratified and choose the "refined tune" option. If you don't know, you have to do a couple of 3rd or 4th gear pulls on a flat piece of road to data log and send to the tuner. The problem I'm running into is that 3rd gear at 2500 RPM (where you need to start your pull) is too slow for the highway so I'll need to go late at night or just when there is little traffic. So I'm having trouble finding a not-to-busy, flat piece of road, that's large enough to do a pull to redline in 3rd. If you've been through this process, where have you done your pulls in the Denver area?
