what are your butt dyno impressions after the hfcs, catback and tune? I'm new to the forum but from what I understand your baseline was 261 and you're now somewhere around 315. It should be interesting if and when semtex will get a tune and see if the headers and intake will benefit from it. If so this car might just match a stock E92 m3's 350 whp and easily match 260 wtq. With the tuned Z making its peak hp all the way up to 8000 rpm and majority of torque from 2500 to 7000 rpm this car will have unbelievably similar power curves to the m3 hailed as having the best engine bmw ever produced let alone the fact that it will be 300 pounds lighter. I hope I get the price I want on a Z soon because I don't know about you guys, but I'm young, looking to mod and wanting to surprise the hell out of some expensive vehicles in the area.
