Are they're any cars running in the low 10s to mid 9s using the TT 6.1 chip or does that stuff has to be scrapped for a fast system or the SD set up. I have 80s n alky with a 5.7 TT chip & my car runs 10s now . what would I gain from losing the maf. Or can it be done on a 6.1 setup that's easier to tune??? Please help me out here guys thanks.
