And it's their dyno probably under ideal conditions with who knows what correction factors. You are doing the right thing looking for hard data on your own. I also agree with RC - too many variables to consider your results. As I said earlier, dyno runs are crap by themselves. For tuning against a baseline, they work well but random runs really mean very little. Actually, there is another recent post showing 0-100kph runs which better shows performance than a chassis dyno.

S1 is fuel timing which produces the torque you feel. S2 is the amount of fuel dumped. Both have diminishing returns and are inter-related.

Now we've learned that RC does not have tuners in the US that can help very much, only customer service people. This is why I called Germany for the technical stuff.

PM me and we can talk about what I have learned from RC and my tests, and give you more info so you can understand your results.
