What are the cam specs? You may not have to change much depending on the specs.What other mods are done? There arent alot of tables to adjust for that pcm. So hopefully you get a pretty mild grind. check the Afr when you get it going. You might have to adjust the ve table some. Have you read out the tune yet?
