I have been experiencing some problems recently with my car, I have narrowed it down to the maf. The maf in question is a Sct Ba2400, I got this maf back in late 04 early 05 it has worked good for the most part. Now that I am looking into replacing it, it appears that Sct no longer makes the 2400, 2600 looks to be the smallest unit. I have two question; first does sct still make the 2400 hundred series maf, second is if they don’t, is the difference between the two great enough that it would require a new tune? I don’t really want to fork out the extra money to get a retune on a combination that until now has been great. I guess if I have to get a new tune I might as well get a twin screw, that makes sense right?
