E-Cutout...need a tune?
After i did my headers/ORY, i got a street tune. after that i installed an exhaust cutout. would there be any tuning to do from just the cutout? in that time i also got a lid and will be installing an ls6 intake so i will be getting a retune anyway.
would ping a bit. Kinda the whole point, to get more
air through the system, meaning you will get to load-
points you would not before.
