I am guessing the amount of lag with this bigger turbo will only narrow the torque band even more. While more power is better most of the time, you would almost have to pre-intercooler spray this thing to get it to spool up fast enough... or get some longer gears to use the power. It looks like a nice upgrade, but I'm not sure the money is worth the 1 second of 1/4 mile time. I do like garrett's work though. I wonder how much a Cobb tuning piece can help this thing.
