Although i am no means a tuner or engine builder i was told to go to the 70mm throttle bodies for max level build when i did my gen 2..i ended up @ just under 15lbs. Paxton novi 2000, 1031rwhp & 985 rwtq...thats with 70 mm bodies & extrude honed gen 2 intake...i will say that low rpm driveability does suffer a little bit..
