You are correct bro. GM says +/- 4 in Nuetral and +/-6 in drive with engine at operating temp. You dont have to compare any cylinders to each other like some say. #1 can be at +5 in drive and #3 could be at -4 and everything is all good. You understand what the + and - is right?
+ is addin fuel to injector and - is taking away from injector
+ is a lean cylinder and - is a rich one
Let me ask you guys this question with built trannys. After you installed everything and put in your tripple disk converter did your balance rates change? Mine went up slightly on my lbz after I built mine. Just wondered if the extra weight and mods done the if engine needed more fuel to maintain the idle speed the computer wanted to see?
