Default engine bogging down

My Saleen is bogging down when I go to get on it. If I drive normal its fine, but when I put it to the floor and the SC kicks in the boost jumps to about 5lbs ( running 10lbs pulley) and the car bogs down. I detailed my engine this morning using 50/50 mix of simple green and water and then used a engine detailer by Gunk called CEB1. I avoided electrical and alternator best I could. Also it surges some when idling. A buddy said I probably had some water or something in my plugs and it would dry out, but I wanted to be sure. thanks Josh

I highly doubt any water could have gotten on the plugs. The symptoms lead me to look at a vacuum leak somewhere.

Also, what kind of intake are you running, and keep it simple for me please, I am just learning these cars. Something like open cone, fwi, or something of that sort will work for me.

Yep, make sure all your vacuum hoses are still attached and snug.

It could be a lot of things. One possibility is that your fuel pump is going bad, and can't keep up with the fuel demand at WOT. I would check your tune on a dyno, and check your fuel pressure under load. If your fuel pressure under load is flat and not rising, it is probably a bad pump.
