What a terrifically giant and ugly car! This thing used to be near undrivable, now it's a pleasure. Really impressed with what you did to this monster.
I have to agree with v8s R Us, it might be better at 550pp. It's a shame to turn down the power, since that's primarily what it does, but it puts in similar times at Trial Mountain with 50 less PP and is a bit easier to manage (at least without Traction Control). In fact it's dead solid, and I didn't do anything but adjust the power.
It's fun at either setting though, and the sheer fact that it can now get around a track at all speaks wonders to your tuning ability. Great job.
