How is your stock ignition holding?
Your plug gap/ignition may be holding you back. It may be time to go MSD....
Also, I didn't see any fuel pump mods in your sig. Were you able to tune the fuel\air correctly?
Also, in my opinion, boost levels above 8 psi tend to create problems on stock internals. Looks like you've got it covered since you're planning on an engine rebuild.
Welcome Aboard!!

The plugs were changed when the blower was installed. It isn't in my signature because I am not sure what kind of plugs they changed it to. The guys at MV Performance build both race cars and street cars. They seem to know their stuff. They haven't suggested changing the ignition.
As for the fuel pump, they are going to be changing that along with the engine rebuild. He has a new fuel pump he wants to try out and see if it will support the amount of power I will be making. If it doesn't, we will be putting in a complete return-style fuel system. He was able to tune the air/fuel well enough with the Walbro 255 that comes with the Vortech kit to support the 385rwhp the car was making prior to the engine rebuild. My a/f was around 11 or so, but I can't find the chart right now to give the exact number.
