[QUOTE="PSD-stroker, post: 1488345, member: 16490"] Hey I recently got the ultimate x tune from ID, I was having idling issues (vane sweep) so I got a couple of revisions. The last one they tested on their truck and confirmed that it was good, it still had the same issue for me. I was checking a few things and reflashed back to the first tune they sent, while doing so I shut off the heater, lights, radio all that, started the truck up and all was good, drive it around and everything is good. Once I got back home I let it idle for a few minutes as the problem was more pronounced at temp, all was good until I turned the defrost on, this caused the vgt duty cycle to go from 29% to 80% constantly, turning the ac on would cause the turbo vanes to sweep. Basically my question is what would cause this? wiring? vacuum? ecm? could this be a tune issue still? None of my other tunes from them do this, I plan to get ahold of them with this issue, maybe they have some insight but I figured I would come here as well. Thanks in advance! [/QUOTE]
