see im running into an issue with my new duct work being 4" to fit the 90mmtb and that the stock maf is 75mm which is small and a restriction. i was going to go SD but found this. this might just be the ticket
SD is a good tune but can be dangerous, and this will still be in the lines of a MAF tune
