Just got a TR 230/224 installed and it made 403HP and 387TQ in an '01 Z06. Dynatech LT's and X-pipe, Borla Stinger, and Donaldson Blackwing.
Idles smooth at 900, up to 1000 with the A/C on. No drivability isses so far. Ever so slight shake to the car from time to time, but not a whole lot more than stock. With the new clutch I haven't been able to hit WOT yet, but I have another 300 miles then hang on!
