Let me get in another couple of runs with a good start, I feel like I can shave off a couple of tenths and add a couple of mph. Off the line is going to be traction limited. Needed more before Evolve and still do.
Once rolling, it is faster across the board. The power band is so broad and relatively flat that the car is simply faster by every measure. Definitely worth the money. I've spent thousands on cars to get 1/4 the benefit of the $800 evolve tune.
