Product was delivered in a timely manner. The 2 day delivery was a little misleading to me since they meant 2 business days so I ended up getting mine on a Monday instead of Saturday. The TSP Stage 1 tune was totally worth the money though. I had Ktuner's OTS Starter 21 and was amazed by the output. Wasn't sure how the TSP could be any better. Immediately felt the difference. The drive is much smoother throughout all rev ranges. Power delivery even when you floor it is smooth. The car doesn't jerk around like the OTS tune does in low rev ranges. Could not be happier with it. The on the fly map switching is also very easy to use. Unlike the OTS tune which switches using the Econ/normal/sport lever, the cruise control switching is really nice because it let's me have the car in the 3 different modes in 3 different maps.
