[Seattle135is]

So I installed the Stage 2 MHD tune on Saturday - so, with the catless dp's, and the M-Perf exhaust, it runs and sounds like a beast. Barring the performance, I noticed the gas mileage improved - I need to use it for a few more weeks to have valid data points, but from my current observation the level of pedal pressure on the gas pedal is definitely lighter after the tune to achieve my regular driving speed/habits in Comfort mode. That being said, the hooligan in me came out a few times to rip it in Sport+, especially in the tunnels in the Seattle area.
It would be interesting to run this Stage 2 MHD 340 against my M2 Comp, with Stage 2 BM3 - I think it would be pretty close.
