Hey, so I’m running a J30A5, stock cats, ATLP Jpipe and 3rd converter delete, 2.5″ open exhaust…. I’m working on a base tune before dyno and would like to know if someone knows the WOT timing on the J’s? I’m pushing 29.5 degrees on the high side.
That depends on each motor...as they are not all the same..also what fuel you running, what spark plugs, etc etc etc
