The issue with Stephen's car was a change with the new Cobb software. It moved a few things around and I had to track it down. On top of that I had an issue with my Cobb key and had to sort that out and rewrite his tune from scratch after we were 4 revisions in.
Yeah that new AT revision COBB recently released changed quite a few things...Thankfully COBB's new map comparison feature helped identify everything that was changed but I'm sure it still took some time to change and move things around...
I'm just trying to get a feel here for how long the re-tune process for a turbo upgrade will take on average and really appreciate the efforts you guys are making...
