[QUOTE="CT9AIX, post: 1300332, member: 6020"] Got back into the MCC thing here recently and I've made plenty of changes to my tune successfully... But I can't for the life of me get the vanes to open at idle? I changed all 3 vane tables, changed all 12 EBP tables, verified the VGT works with other tunes and the rod itself moves freely. I unplugged the VGT and the vanes open right up, plug it back in and it goes back to 50-60% or so and that's about as open as it will go at idle. After I flash the truck the VGTDC will hover around 50ish, I give the truck some throttle and as the RPM's come down so does the VGTDC, but then the VGTDC slowly climbs back up to the 50ish area. Am I missing another table that needs to be modified here? Thanks in advance from the rusty weekend warrior tuner lol [/QUOTE]
