Sidewinder momentarily cuts out

One other thing that could be happening is that you are tapping the rev limiter.

Definitely possible

My thoughts as well.

The first year of the Winder, as aftermarket muffs were coming out, it was reported they would over-boost with no tune.

It’s definitely making sense. I’m installing the old muffler tomorrow.

A bit off topic but do you fellas know what rpm the limiter starts at ?

I've seen your problem before and it definitely sounds like over-boost. You'll find out when you try the stock muffler.

If I remember correctly, I think 9600

Wait, you're running an aftermarket muffler on a stock sled?

If you are, that IS the problem. It will overboost and hits the boost cut, killing the sled momentarily. On top of that, most mufflers will also allow the engine to run too lean. Only one I know that does not overboost and hit boost cut and run too lean is the Hurricane Hindle.

Thanks I will try the old muffler tomorrow

Did switching back solve the problem of cutting out? My new to me stock 18 with a aftermarket exhaust is do the same thing.

Do NOT run your stock SW with a high flow muffler! You need a tune that is catered to the higher flow exhaust and safely allows for the higher flow through timing and fuel adjustments.
