P101 MAF Performance after D1SC installation
The code basically says that the MAF reading is out of tolerance for the 'expected reading'. You car looks at the MAP, TPS, and RPM, and knows a ball-park figure for how much air the car is suppose to flow. The MAF is then allowed to report a value that deviates a certain percentage from this 'expected' value.
Supercharges, naturally, throw this all out of whack. Just check the MAF for any obvious damage, make sure the car is running fine, and if you don't find anything have it tuned out.
