I have a feeling its my MAFs but am not sure. What else can cause the beast to be slowww? I already ordered new spark plugs will be putting them in tomorrow. When I did the MAFs test my readings were pretty off. At idle it reads 0 liters, at WOT in 2nd gear I can't get it past 105 anymore. I have already replaced the air filters. I had read that there is a group buy on MAFs, can someone please point me in the right direction. If anyone has any suggestion as to why my beast is slow, your help would be greatly appreciated. Would really like for my beast to be doing this :M5launch:!
