I think you need to get the truck tuned for cutouts.

I ran my qtp's right before the muffler NO TUNE you shouldn't have to tune it. I own an SSS and I ran a 14.8 with out a tune and the cutouts open. Try it out, you will also like the sound it makes.

To get max performance of cutouts open you need to tune. Played this game before trying different mufflers on my procharged camaro. Each one needed the tune tweaked.
