Hi Paul, I really like the idea of the direct connect dyno. It takes one more variable (wheel rolling resistance) out of the equation. Should give you more consistent results. Im pulling 79HP/L on my 3.2. You should be able to pull 285HP from your 3.6 w/ exhaust work, maybe 290/295HP if you eliminate rolling resistance. BTW, if you want to see the details on my exhaust mods and dyno results, I posted a vid several years ago here: https://youtu.be/MdCQg2tJFYg.

Hi Ike, Sounds like you have more depth on the Porsche tune than I. We ran the car back to back with the stock tune vs Fabspeed. It was an honest 4-5 HP. Not huge, but honest. Looked like the achieved it through a leaner A/F ratio. That said, when I spoke to Fabspeed they clearly outsourced their tune, but I do not know to whom. Fabspeed acted as the intermediary. It took them 2 tries to find the few HP, but they did. As I mentioned, they are no longer offering tunes as the EPA shut them down. Disappointing, as the number of tuned cars is 0.001% of the overall car population, and most of these cars see little street time. They are chasing mice nuts IMO. Government agencies finding more reach than value (I'll stop my political rant now, sorry).
