Thanks for the info, guys. I honestly do not think it's been tuned since, after more research, I found the CAI to just the short tube, filter,and box from Roush. Which is listed as not needing a tune on American Muscle. Its one of the cheapest ones on there, so I'm going to assume the last owner was cheap or on a budget and definitely didn't put out the cash for a tune.
But, I just bought a weighted shifter from Flossy and a Barton Shifter for my first mods. That stock shift is so awful. After that, I think springs are next, but then gonna look into a tune.
