hi guys, first post in the group. read a lot of threads and there seems to be a lot of information out there on which has been very useful!
I was thinking of going stage 1 with my mk5 GTI and was going to order a an oversized RAM AIR INDUCTION KIT as well. if I fitted this prior to the stage 1 map would this effect the MAFs reading of the airflow to the engine and cause any warning lights or problems Because of on increase in air flow?
