OK I guess I need to be a bit more obvious...
I think you meant to write shiftlock.
Tried the NSX Type-R tune up and it weren't half bad.
The Honda ITR is gold I love it. Not much of a tuner myself but I know a thing or two on them. However where I'm not gold in tuning, I'm gold in driving. I follow the line 93% of the time while the other 5% I take a diffrent approach.
What better way to learn the basics right? Well again man, your tune for the ITR is gold major props to you. I hope. GT5 do something similar to FORZA3 tune shop that users can do and get paid. Because you just got a loyal customer haha, till then stay gold yo
