Some Weistec stage 3 numbers for ya
Last Saturday me, and my wife went to a dyno day at Premiere performance in SLC. Utah, and after 3 pulls, we ended up with 636rwhp, and 515rwtq. So pretty much "as advertised"!!!
At the 1/8th mile track we always go to in the summer months, my wife got several 7.6-7.9 timeslips, with a 7.5 best at 95mph. The best before the blower was an 8.7, can't remember the mph, but around 10mph slower I'd guess. Also, I usually 60 footed around a horrible 2.1- 2.3, now it's always in the 1.8 range, with a few in the 1.7's. The "tune" that went along with the blower seems to control the trans/clutch much better than the previous tune.
Either way, gains of over a second in the eighth is simply huge imo. So if you're thinking about a blower for your C63, this is a good one, and aside from changing the oil, and showing off the engine for others, the hood hasn't been opened since the install, very well engineered to say the least.
But now it's time to throw some money and work at my 2012 5.0 gt Mustang, and see if I can make it kick my wife's butt at the track next year, wish me luck, as I'll need it, hahaha!

Which tune did you go with? tweaked weistec's? Just wondering what differences between the 2?
Also for your mustang project get you a shelby GT350R instead
. Should be another track beast!

10 C six trizzle
stage 2 since 13kmi. have 39k on it now. so 26,000 miles.
trans lasted till 28k. did a stock rebuild and upgraded valve body. so far so good
p.s. i think your torque is a typo.... maybe a 615 instead of 515? Enjoy it. Those new 5.0's are quick. You should be fine just make sure they tune it properly. I've heard something about the rear cylinders running to hot or something and melting stuff.
