Another big lift this weekend. I've been fighting an idling problem with the Sniper, and finally figured it out. My idle would not drop below 1250 for anything. It acted like there was a vacuum leak, but I couldn't find one. After speaking to a Holley tech, they sent me a replacement IAC. I put it in and . . . same issue. It turns out one of the primary throttle blades isn't closing completely. If I hold the throttle lever back to force it more closed, I can get the idle down and the IAC to kick in. So I need to figure that out.
I did finally add a fuel pressure gauge so I could confirm the pressure being provided by the pump.

It runs great with the exception of idle. On the road it's fantastic. Much better performance than the Holley carb that was on there, or the Edelbrock AVS2 I installed. Of course part of that is running the Hyperspark system.
While I was mucking about in the engine bay I decided to clean up more wiring and get rid of the starter relay on the fender. I've already replaced the starter with a newer model that's smaller, high torque, and has a relay built in. That just meant I had to swap around wires, move some to the positive battery terminal. The MSD relay in the photo currently supports my two cooling fans. It leaves me with room for more, like the fog lights.

Now that I'm pretty happy with the Sniper, I can finally install the right air cleaner. I had to add a 1/2" spacer beneath the cleaner so it would clear the distributor, but I'm pretty happy with it overall.

Next up . . . cruise control! I've already completed installing the mechanical bits. Tonight, I'm going to wire it in. I'm using the Dakota Digital cruise module. Since I'm also using their VHX gauge set, GPS speedo, and Bluetooth fan controller, I'm well and truly part of the Dakota ecosystem.
