That issss interesting. My rpm gauge reads around 2k at idle. Im guessing thats because of this issue. When I stomp on the gas when in park, the boost will jump up to maybe 5psi or something, is that correct?
I had this cluster sent to me with the 87 engine that I bought, and my old(84) cluster didnt read high like this one. Can I just take the board out of the 84 cluster and stick it in the 87 cluster???? Are they the same?
Sorry for hijacking your thread. I didn't mean too. This was just a really cool insight into what happens with these things. Sounds like you've found your problem grandnational6!
