Power loss with cut out open??

What's the AFR and injector duty cycle? Maybe the injectors are on the border line and with the added air from the cutout open they are shutting down.
I would think a tuner would look at those two things pretty quick after a power loss that big.

The o2s are tuned out but there still in the slp y and the cut out is under the rear seat. I got the car out earlier to beat on it a little to see if I put tell any differance but the cut out got stuck open before I could really do any adjusting.

The car had the full exhaust on it when I bought it. I was pretty much given the cutout so I was giving it a shot.

idk about the pump a buddy of mine has a h/c/i car that makes 454rwhp is on the stock pump but with bigger injectors. you may not NEED a new pump but for the price you might as well just to eliminate that as being an issue. if you want a pump your not gonna max out until you start makin big power thats still intank and basiclly a stock replacement get a deatschwerks pump they look like a warlboro but flow much more fuel and have a nice warranty and are pretty damn cheap

We tuned it. It was not a fueling issue that caused the loss. The injectors did reach 94% with the cutout closed. But was lower with the cuout open. We did discuss him needing larger injectors.
Once the tune was adjusted for the cut-out open it still net him a loss of around 38hp. The car went way rich when the cutout was opened (not lean as one would guess).
We have seen gains of varying levels wioth cutouts but this is the first time we have seen one lose. My thoughts are that his cam/heads combo needs the backpressure.
