Running rich

Well from reading about another rt with the same mods as me and no tune he had his a/f at around 10.5 so im guessing mine is the same. I know the tune is the only way to really fix this but is there anything i can do in the meantime since theres no tuning for 2012?

Only way to tell would be to have a wideband installed or make some dyno pulled with an A/F probe. I would be leering of doing anything without knowing what your truck is actually doing.

The other truck that has the same mods belongs to a guy that tunes gm vehicles here in Houston and he bought his rt and put it on the dyno and that's where I got that a/f ratio from since it's the same type of truck with same mods
