Well, got the 3rd MAF sensor today. Installed it, drove it for 10 miles, running great. Lotta junk out there I'll tell ya. If it ever goes again, going to a lt1/ls1 style MAF. Running like a bear with the SMC alchy kit and 25 lbs boost, no knock! Gotta get to the track! Betting low 12, high 11's. Was running high 12's before with 18lbs boost w/ 110 fuel.
