So here it is... I foresee doing an exhaust air and tuner upgrade soon. Would it be better to go with a stage 1 air or a stage 2 air if I also wanna do head work with in the next 6 months later?

 

I would go with the air cleaner that you want to run and get a tuner that will allow you to tune it throughout the life of your modifications that also meets your expectations. My vote would be the TTS or the SERT....

 

Stage 1 A/N little sucka just fine here.
It works fine w/cams too if that's your question?
