GT3 82.5mm Throttle Body!

odd. i've had no issues. when i first did the tb mod i hadnt swapped the airbox yet and was using a bmc airbox with an oiled filter which fouled my maf. once i got the airbox in every thing has been perfect, with a season of track days to confirm.

It seems to be the larger maf housing from the 987 that causes my issue. I put a restrictor inside it to make inside diameter smaller, which helps some. Had two different softronic tunes, one works slightly better other not at all. I need to use the original maf housing from stock box and adapt it on there I guess. Just dont want to go that route until I can afford IPD and larger tb, Too many other hobbies....Just turned 10, 000 miles on engine in two years.
