QTP Electric Cut Out

[T/A Addicted]

I purchased the adj Borla Cat Back 2 months ago and was playing with the restrictor plates to see what I liked. I read somewhere that after changing the plate it would take the engine aprox 300 miles to self adjust to the change. Is that right? Also I just put on the QTP cut out in place of the plates, how will opening and closing it affect the self adjust? Any help would be greatly appreciated.

The ECU on these cars is short of a home computer in terms of power. It is a self learning ECU.......what I mean by that is that it learns and stores fuel and spark curves. Removing a restrictor plate in the exhaust is more then likely not going to affect it that much. And the computer usually will figure it out in a matter of 5 miles or so, not 300. Frost (computer expert) usually says after major mods/computer tune, that the most it would take would be max 100 miles. Hope that helps.

yeah thanks alot thats what I was looking for

300 miles sounds like a bit much.
Most minor mods will be 'learned' within 30 minutes of city driving.


Also, I would stay away from the QTP e-cutouts and go with the DMH versions.

why stay away from qtp

why stay away from qtp

Warranty isn't as good.
People have had issues with the butterflies failing.

why even use the cutout just put the big plate in and bolt it back together sounds better
