98 PCM is a sad story, no custom OS available. Ross had plans, but they are on the back burner.

What is the max maf frequency you are seeing @ 7 psi?

You can play with the stock OS in open loop and use PE to kick in post 105kpa for extra enrichment. Not sure on the spark front though, you might have to talk to the stock OS FI guys.
