However I'm going to go with a dyno tune when the time comes.
I believe I read our cars can adapt up to a 20% increase in air volume before running lean. The MAF house size is programed into the car's DME, so if you change to a larger MAF house the MAF sensor can not correctly determine the amount of air going into the engine. I think it will even throw a CEL when using the 987 MAF house.
