they're still working on tuning the car, they havn't found all the ins and outs of the computer, id say 1-2 more months and you should be able to tune out MOST of the torque managment.
can you believe gm put so much torque managment in these cars, that some of the a4'* cant even peel out? most can, but some for some reason cant, and its been traced back to the computer. even the manuals, thanks to drive by wire, have a good amount of torque managment
what torque managment is (im sure most know) is a computer feature than pulls back alot of power at shifts, to save shock to the transmission. well now its much more aggressive, you dont even put down all your power in 1st gear. you put down most in 2nd, but stilll not all. its gm'* way of making the drivetrain live past warranty
what really sucks is the 06 GTO'* are using a completly different computer setup with much more advanced encryption that will be alot harder to crack. the 05'* was already completly different. gm may change it everyyear.
but otherwise the 05 gto is by far my favorite car, changes over 04 include
newer bosche abs system
6.0 ls2 (50more hp than last year)
completly new computer, now drive by wire instead of by cable
updates for m6 to hold more power
bigger front brakes
dual exit exhaust, new rear bumper
im sure there'* more that i cant think of, check out ls1gto.com
all the small little glitches in the car are easily fixed by the aftermarket
