I have been searching the forum for a little while, and I have been unable to come up with a solution. The Cobra in question has full exhaust, 115mm throttle body, 2.8 upper, steggy stage 4 ported blower, stock injectors, stock fuel pump and a kenne bell BAP. The car was tuned by Bob Kurgan, who unfortunately is now halfway accross the U.S. with an Xcal 3. Recently the car likes to hesitate badly during Wide open throttle applications. I thought maybe I blew the fuse on the BAP, but I just checked it earlier and it's fine. It is the 40Amp BAP. I turned the key a few times to see if I could hear it kick on, but I'm not sure if all I am hearing is the factory fuel pump. I could have swore I could here the BAP running, but it's been awhile since I have paid attention at start up. The car idles just fine and drives great, but at WOT it feels like it's missing bad. It almost feels like the car is holding itself back. Do you think I'm running lean, and that's why it is falling on its face? The car does have NGK TR6's that are pretty new. Any ideas? This is definitely irritating the shit out of me.
