If your car is smoking blue alot and has a funky note at idle you cracked your pistons. it has nothing to do with your tunning. OIL is NEVER supposed to come out the exhaust. If your car smokes BLACK then your running rich, that would need some tunning. Since you were runnung a FMU at 15psi with no msd BTM I would say your pistons are SHOT. 15psi + stock timing + FMU = SHOT ENGINE. Convert to obd1 and get tunned correctly and forget about blowin up. Let us know how much oil you burn in a week... 2 quarts?
