Just got back today and got to drive my car today with the new setup. Car is awesome but due to rain I couldn't have too much fun. Over the phone the shop told me they did a SD tune on the car but I noticed the stock MAF was still on. I know usually the MAF goes away and a single coupler is used. I guess my question is, is this normal and would this be holding back some power here? I plan to buy a new coupler soon and ditch the MAF.
