When deciding (suggestion only) what to do-stage 1 etc... I look at the end outcome I may want.
Just stage 1, ac only (tuner needed) or exhaust only, I would shop around some-research- you can probably get a better performer and lower cost. Exhaust and ac, I consider it stage 2- Pick your choice exhaust but will need some sort of tuner to richen the fuel.
Now the big question, are you wanting to stop there or perhaps change cams later on- stage 3 as I put it.Then you should consider a tuner that will adjust for a cam change. Some tuners are not able to cam changes and timing.
I warn you, the more you get the more you will want. Don't ask me how I know LOL
