I have 2.5L bottom with mildly ported heads with bigger injectors. My air fuel mixture ranges from 10 to 11 across the rev range (very rich in my opinion), dyno at 180 hp at the rear wheel. Thats why I'm leaning towards the MAF since it will give more air and improve the A/F mixture then eventually more power. Am I right or should the cam be first since more duration will result to more air inside the engine? I'm getting confused but I will also do the cam when I have enough budget. Thanks.
