SCT Eliminator Chip necessary?

I've ordered a MAC o/r h-pipe for my GT, and I'm wondering if I should just get the MIL eliminators or bite the bullett and get the SCT chip.

Will the car need a tune with the new h pipe, or will it run just fine with the MIL eliminators?

I am EXTREMELY hesitant to buy the chip and put it in myself. It looks relatively simple, but its messing with the computer, which terrifies me.

Will SCT be able to tune the car to the o/r h pipe? (and if so, will it still be necessary to buy the MIL eliminators, or will the chip take care of the light?)

Its a lot of questions I know, but I know many of you have already made these mods.

No matter how hard you try, two stupids do NOT make a smart...

I would buy the handheld, it opens you up to being able to compensate for mods such as gears, off road X, different tire size, etc. without having to send the chip in to be reprogrammed, you can do it by yourself in 5 minutes.

MIL eliminators seem to be hit or miss on the 4.6 Mustangs, sometimes they work, sometimes they don't, but the tuner always works, since it turns the rear O2 sensors off at the source.

If it weren't for physics and law enforcement, I'd be unstoppable.

The car will not need a tune for the o/r pipe (though one could never hurt) but I would suggest a handheld tuner as bullitt said.
