The shift changes between 1-2, 2-3 are vastly improved, it is very smooth to drive hard, and there is no dip in power when driving through the gears. Power is relentless, and smooth.

I immediately noticed an improvement in low end performance. I could feel more power and torque off the line and could wind out 1st gear, which is usually useless with stock tune.

After spending a ton of money on the hardware, this software finally made my car take advantage of it all. I cannot wait to continue tuning. Oh, and of course the support is always awesome.
