Im running Daz(RIP) tune. I'm on stock turbos, with Wagner IC setup, walbro 450 fuel pumps, gutted Main cats, Milltek Resinator Midpipes with 3" straight pipe the rest of the way. Full Apikol\stern mount setup. Stasis 4:1 centerdiff, Jhm short shifter...: soon to be doing injectors, water/meth, and bigger turbos. The clutch slips a little under hard load like 3rd gear cruising to full throttle. I mentioned the smoothness of the clutch because I EXPECTED IT TO BE MORE AGGRESSIVE. I actually love the way it drives. I WOULD HAVE GONE WITH THE STAGE IV if I'd have known the stage III endurance was so smooth. Bi assume the jump from 3 to 4 won't be that big of a difference in drivability.
