Because why not?
At this time, I'm contemplating buying the licensing so I can tune 05-06 GTOs if there would be some interest in getting some tuning done at the meet. I'm going to be buying it for the 09 G8s because the GXPs especially have a lot of room for improvements. I'd be able to do basic things like skip shift disable, cooling fan run times including after engine shut off, some basic idle and driveability tuning if you've done some mods, disable O2 sensors if you run without cats, etc. Without a WB O2 I can't really do WOT tuning but cruising would be easy to do. Again, there'd have to be some good interest because the licenses aren't cheap. I'm thinking $50 for a tune, maybe a bit more if you want some cruise tuning done. Any interest?
