Mid pipe for a Vortech supercharged 2005 Mustang GT? Hi, i have a gt05 with vortech HO, bassani axle back and bassani xpipe, i still have my stock headers and cats. I want a better mid pipe with better cats, better flow, or off road? But i dont want to mess with my custom tune, or i am going to have to? I have predator without the option of turning off 02 sensors, but i really want off road pipes? I want a little gain in throttle response and a little more torque, thats why i want this? Thanks

If you take your catalytic converters off (off-road pipe) you will need a COMPLETE retune for that Vortech.

You really think so? Other than the rear O2s, it shouldn't be that big of a change...

Your WOT fueling will be off by more than 20% in some cases.

I'm guessing on the lean side?

Yeah, it's not like you'd have to redo ALL of the tune, but the tune has to be rewritten, you can't just make adjustments for it on the handheld.

You could make WOT fuel tweaks but that's all.

Not to the magnitude that it needs. Not anywhere close.

Sure, I'll buy that. If you weren't so darned far away, I let you tune my car!

I fly buddy. More than half the cars I tune aren't even in the same state as me. I'll be in Florida at the end of this month.
I can also email tunes to you for your SCT XCal.
