I have LTs to catted Y to lm2 right now,,,, and what i feel is a good tune.....The questions are, if i were to get cutouts 1. single cutout, or two....2. Will the cutout just add HP or will I need a re-tune? Will the added flow mess with my A/F ratio I'm still pretty new to all this....Thanks for the help.

If you plan to cam the car later I would not tune it now. But if you are done moding, tune it now. The cutous dont add much HP, maybe 5-8 hp, they just sound bad ***.

A retune isn't necessary but to benefit from any gains you will need to retune.
