Have been using 4 inch mega maf for last 10 years but had to use tornado in front of turbo to stop maf back flow that caused erratic idle and dying when letting off gas quick. Bought 85 mm truck maf Delphi 10043! Set gen2 maf in to ls1/ls6 85mm starts and runs fine at idle and low speed but bucks and goes lean at anything over 2 volts on tps. Same thing with 3.5 lt1 and ls1 aluminum setting. Tried a different 10043 maf same thing. Runs good when I go back to stick type maf.
