Default Does cutout effect A/F Ratio or tune?

I have a dyno tune on my car prior to installing an electric cutout in the I Pipe just before the axel, just wondering if this will have any effect on the A/F or tune????

Seems to drive just fine, just looking for advice or confirmations. Thx.

It could run better or worse with the cutout open since it was tuned the other way. It depends on how your tuner set up the car.

Driving it it seemed OK, I was too busy enjoying the noise!

i had a friend tune his car thru exhaust, then to see if he could get more numbers thru cutout. did fine with this. he opened the cutout at track. ran like a champ.
