[QUOTE="Robert Francis, post: 8628041, member: 3393"] You'll hear varying opinions on whether you need an upgraded MAF. If you haven't had any problems, just switching back to the stock air box shouldn't bring about any problems. The only way to know if you really need any MAF changes is to find the number of "counts" on your MAF at WOT - and unless you have a device to read them yourself, the only way it can be determined is on a chassis dyno. Your tuner can do this for you and tell you how close you are to maxing out your MAF and recommend whether you need to make any MAF changes or not. I had a setup similar to yours (6 lb lower pulley) and when I asked my tuner to specifically check the counts whiel having soem dyno work done, he said I did not need any MAF changes. However, many others seem to have had different experiences. And many decide to upgrade their MAF to be "on the safe side." How often this is needed, just isnt known. If you need to make a change, there are generally two ways to do it: replace your MAF with an SCT MAF or use the Diablo MAFIA extender. If you need to upgrade, most chose to upgrade by the method their tuner tunes. The tuner I use, primarily tunes with SCT software so when I upgraded I chose the SCT MAF. However, the Diablo MAFIA also accomplishes the same thing. And many tunes work with both SCT and Diablo. r In either case, if you do need to upgrade, you will need to have your tuner set it up for you. [/QUOTE]
