to tap or not to tap?
Ok, I just hooked up the comp and upgraded to some mach 2.5's. The question is will it be night and day difference with the pump tapped and therfore being worth the risk of killing the vp?

I noticed a big difference when I tapped the pump with my comp. I was also worried it would kill the vp, but I decidd to risk it. Ifthe pump was weak I wanted to know so I could get it taken care of. Just my $.02

I see that a FP guage is missing from your sig. Get one first to check your fuel supply is good and if it is tap it. Get the Stealth cover it is sooo much nicer.
Look at upgrading your fuel system too. You're gonna need it!

There is a chance it will survive. But there is a chance it won't...
The Vulcan kit seems to help... You could install the FP gauge and see what your pressure is. And if it is good go ahead and put the box on.

your only getting the benifits of the timing until you tap that wire. With that being said, monitor your fuel pressure closely. Your engine will demand more fuel than the lift pump can provide on the higher levels.
