mod advice
#31
i'm new to this site and have a new 997TT. i flashed the giac software, both the pump and race version. what a difference. i also installed 200 cell cats and a performance muffler and headers. they tell me it's 600+ hp with the race software.
my question is also about innercoolers. will the gt2 innercoolers do enough to justify the cost?
