I have a 4:1 center dif, per Steve. When I get the car back from AMD, I'll do up some acceleration and dash videos.
The car has to be buttoned up as the intercoolers are being rebuilt due to bad leaking (new cores are being welded between the stock end tanks). The IC rebuild is more affordable than any aftermarket option and will have more flow than stock as the cores are thicker. We're doing the same number of charge rows as stock, 14, but apparently there can be as many as 17 charge rows for yet more flow but I didn't want to wait 2 months for the custom cores to be built, not to mention the extra cost. Also, I never plan on running meth so I'd prefer better cooling to maximum flow. Lastly, we are keeping the boost down on my car for now as one turbo seems to be nearing the end of its life as evidenced by a fair amount of oil in one of the IC's and some noise, as well as a slipping clutch at about 500awtq. CM stage 3 is not advisable for these cars. I'll be getting AMD's clutch when I'm ready, which seems to be more than adequate for the power that these cars will produce.
I drove it for a weekend with the functioning ABS/ESP tune at stock power levels, soooo much smoother and nicer than the GIAC tune that just didn't seem to act right with the manual transmission. Props to AMD for taking on the challenge and figuring this out, apparently it was no small feat.
