If somebody calls about sending their PCM and when discussing their modifications they tell me have a ported (I have another name for that), aftermarket (won't post the name here, a sponser), or aftermarket MAF ends I simply tell them I can't help them unless they want to change back to a stock unit. If the vehicle is here, I have no problems re-scaling the MAF tables to corect for it. Just takes more time, for about a zero power increase. Through the mail, no way. Have had a couple indicate a stock MAF on my order form, to have them call back with something like 20% or so fuel trims. After further questioning I find they have aftermarket ends installed, but they still call it "stock". Guess they think the electronics is all that effects that. I've been preaching this since 1994, took a long time for some guys to believe it.
I am very amused when the maf looks like it was ported with a chainsaw however
WheelmanWS6- Many people are reluctant to believe that the stock screened unit is the best option but you are right on the money and I am glad you're happy with the results.
So to go in the other direction, since I had my car dyno tuned with a ported MAF, when I go back to stock, will I have to make some changes (I don't think I told the tuner I had ported the MAF because I didn' t think it was important)
