I've posted this in the hot air forum a long time ago. I got mixed reviews. I also searched this and didn't really find any solid evidence. So here't the question. The ideal is supposed to be high 700's to low 800's...so my buick sees low 900's high 800's with my otc 85 monitor. Some say that the otc monitors read higher then the others. Why would they do this? Doesn't make sense to me.
Is this true? If so, does it include the 85 model? It's a very old one 
Any information will be helpful as this is making it impossible to tune my car.
