Yep if you have a well setup exhaust cut outs just make noise.

I have a supercharger on it. Full bolt-on. all it does is make noise, and it feels like when its closed it's faster. I figured it'd pick up some hp up top atleast. Sucks. It was dyno'd, and tuned for.
07 nnbs ecsb 5.3, full bolt on, Blown. 6.0 swap going in now, and maybe 100 shot. To be continued...
Opening the cutouts makes you lose back pressure and thats what causes you to lose bottom end. Back pressure is good to a certain point. Especially with a supercharger you should move off the line pretty quick.

true story. my truck lost 15 rwhp with the cut out open on the dyno and the mid range was also dog meat. You could def hear the difference with it closed and open, not just the noise but the motor wound out easier with the cutout closed. just a bunch of noise, sounds cool, but still just noise.Originally Posted by sleeper1500

If you're not tuned for methanol, I'd recommend one of two options
1 - Run 100% distilled water, no meth
or
2 - Tune for the meth. Pull some fuel and maybe add some timing
~ Forged engine of some type ~ Ball bearing turbo of an unconfirmed size ~ 4L8000 trans ~ Beefy fuel system ~
3. Up the boost

That's what I did. 2 methanol nozzles later, the stock MAP is maxed out
