you guys are funny. fabios car is absolutely visceral on the street.
and about it being peaky on power (which s54 isn't, exactly?), car getting too hot @ 100%, who the **** cares. a stage 1 HPF car will smoke 99.9% of cars on the street running at 80%.
if you wanna build a better turbo kit yourself, do it, the guys with HPF kits will dump them and buy yours. until that day, there's just a lot of hot air in here.
