01 Trans Am

I just recently put headers on my car and got it dyno tuned. My question is that if I switch from my cb/ory setup to td's and do my free mods now, will I need to get another tune? Will this affect my performance or make me run rich/lean again? Thank you in advance.

No, save that money for future mods.

Potentially yes it may affect your tune, but I doubt by much so I won't worry.

Adding duals may have an affect positive or negative or maybe no change at all, it really depends how good the dual setup is compared to the current Y setup. Going to duals does NOT automatically mean better.

I vote save as well.

after you do duals and free mods i would atleast have it checked for piece of mind, even though it shouldn't be far off at all.
