New Tune Question???

[morstang05]

I got an 05 Gt 5 speed. I have an SCT Tuner with three tunes. Current mods are LT headers , X Pipe w/ cats, CAI, Steeda Pullys, steeda susp. I have stock gears but plan on getting 4.10's pretty soon. My question is, since I swapped to spintech super pro street mufflers and getting 4.10 gears, will I need another tune? Getting one isnt a problem, but if its not necessary then I wont spend the money.

Mufflers won't affect anything, but the gears WILL. So yes, when you put the gears in, you'll need a new tune.

I ordered a tune with my CAI, and later installed my exhaust and MRT H-pipe...should I re-tune?

Is it an O/R H-Pipe? If not, and you left the stock manifolds on, I doubt you need to, but I'd check with who you got your tune from just to be sure.
