So I finally got my 370Z tuned last week and honestly the car pulls way harder up top, which is great, but now I’ve noticed something weird. When I come to a stoplight, the idle sometimes drops to like 500 rpm for a second before catching itself, almost like it wants to stall. It never did this before the calibration. I took it to Dyno Star Workshop because a couple of guys at the track recommended them, and the driveability everywhere else is fine, smooth cruise and no flat spots. I’m just worried this idle thing might be a sign of a vacuum leak or maybe they didn’t adjust the throttle follower settings properly? I called them and they said to bring it back so they can check the logs, but it’s a bit of a drive for me and I’m wondering if this is something that settles after the ECU adapts for a week or two. Anyone else had a similar experience after getting tuned? Should I just go back immediately or give it some time and see if it learns? Really don’t want to seem like an annoying customer if this is actually normal.
