man i must have a weak maf and map sensor. put in new maf and it reads at 5700 37 and the map is going to 14.5. so as far as i know that is right with the map.

what are you reading your tables with zden and randy grabert???

i guess were not talking about the same thing, which pid are you logging with. I assume we are talking about manifold absolute pressure?
