like i said i have the d66 and imo it blowes a stock turbo away! also like i said when i did myn i did do tunes as well, so i would try and do tunes and a turbo around the same time to get the full potincal of the d66, and i am hopeing glen also see' that when he gets his up pipes on, other than the turbo from yiyto turbo in p.r most turbo will set you back 2 grand or more, i got some info from ats and the have a turbo set comeing out at the 1 of the year new turbo{with has all same spics as d66} and ic, 35 hunded bucks! like i said imo d66 is a good way 2 go unless you have a few grand just laying around, not sure how many guys have the d66, all i no of is me and glen,
