I have the 8,000 rpm aftermarket stock cluster kit installed and the pcm put out the wrong signal and after talking to avatar "critter" from "lone star dyno" i sent my pcm to him and he did the required mods and tested it on 2 different tachs before he sent it back. He said the signal needed to be changed in 2 ways, i believe from 4 cyl to 8 cyl and had to rescale it. He said this worked better than the pullup resistor, but i can't verify it. He was fair and took the time to double check it before sending it out. His name is Terry.

I did the ls1nova cluster changes and between eric (ls1nova) and terry it came out great.
