I pulled the vacuum line off the bump valve to see how much boost it would make and the dash light came on.. I reinstalled it and its been 4 days and the light is still on. How do I reset it?

Also I have a 2002 PSD auto and it makes 14psi stock and 18psi with the vacuum line pulled. Is that normal boost? I thought it would make more.

 

You can reset the CEL by disconnecting the batteries for a few minutes. Once they're disconnected, turn on the headlights to drain any residual power in the system.
18psi boost is considered normal. To hit that, you might have to be pulling a fairly steep hill at WOT.

 

Thanks!! Its a free mod but I dont like the light.. Does anything happen then the light comes on.. Pulls timing? Anything bad? I could just unplug the lamp in the dash!
