I was trying to get him to stay away from canned tunes, Marshal...
Lol but Will knows what he's doing, that would be the only canned tune I will run in a GP.
Now if e talk canned tunes in general, it's better if you get the canned tune in the car when its new. Like with a 2015 car, there is almost no differences between one fresh from the factory and one with 10k, engine and trans wise. Less that could be slightly off in the canned tune.
A GP with 100+ thousand miles? So many things could have happened to that car, nobody can know how it truly affected everything.
