I like it. You've turned this handful of a car into a competitive racer. some of my other cars at 550pp put in slightly better lap times, but this one is fun to drive, can hold it's own, and handles better than some tunes I've seen for it. (I left off the exhaust and intake to get maximum power-to-weight at 550pp where I ran it).
I ended up with brakes at 8/6 and LSD at 8/8/33 (on racing tires), but that's just personal preference. I do notice the nose really seems to dive down under heavy braking, but it doesn't seem to effect performance much and I'm not sure that feature is really a "problem"
I'll check out the changes you made, and if they make the car easier to drive (heaven knows it can be a little tamer) I'll update the tune.
Thanks again sir!
