Creating a comprehensive tune for a new configuration is a time intensive task. A full tune takes many many hours and most of it is not done on a dyno unless you have a load dyno at your disposal. The hard part is part throttle and the majority of shops don’t spend too much time on it (or at all) for various reasons.
Our remote tune for full bolt ons has many many hours into it. Most of that was street time dialing in the hard stuff. There are shops that understand this. There are shops that don’t and deliver a mediocre calibration.
I’m about to start a full calibration for a 17 ZL1 with headers, pulley, and E85 (with our upcoming ZL1 FF kit). Fortunately it is locally to me but I will spend at least a full day just dialing in VVE and VTQ before I ever get to WOT. I will also be using the Plex Knock Monitor to ensure the timing map is not going beyond safe limits for the combination.
