When I hit the throttle hard my engine kinda acts like it doesn't have any power and when I lift the throttle some it picks up and takes off like normal. I've taken the Maf off and cleaned it with electronic cleaner and no help. I've even taken sensors out of the throttle body and cleaned them to. It seems like it does it only when the supercharger is on it. Its pissing me off cause it ran right for a couple days of me putting the s/c back on it. and then it does this.

 

I've even put the stock maf on and it helps in one area and hurts it more in another. The Maf I have on is a Granatelli Maf by the way.

 

anybody got a thought?

 

Cats Clogged? Tune is off? you doing any data logging when you test this? what kinda blower you running? how much boost/what pulleys? you could be getting belt slip and its dumping all the fuel for the blower, and you getting no boost...

 

Like Injected1 asked, which blower? Magnusson might have the bypass valve stuck open, others a loose intake tube or leak. Clogged cats will cause that, especially if you are running pig rich or ultra lean and cooked them.

 

No cats nelson turned the O2 off. Powerdyne s/c. All tubes are tight. Nothing to data log with. No belt slip. As soon as boost gets around 1 psi is when it starts acting up. With the s/c off, it runs fine.
