diablo quick question

[Madcity T/A]

there is a dyno tune done by the guy before me and I just got a preditor to ajust the tire size and get rid of codes for the LT's. I plan on getting another tune after I get H/C but for know my question is can I change the tire size and delete codes without changing the rest of the tune? and when I plug it in will it sence the tune or delete it?

The tuner will not work with your car. If you can is stock or has minor bolt ons i would take it to a GM dealer and have your PCM reflashed. Then install The performance tune from the tuner and modify all the other parameters you bought it to modify.
