    • CA Automotive Claiming 60 hp gains on pump gas with their Stage 2 M5/M6 V10 S85 tune?

      Here we have graphs on a dyno dynamics of the Stage 2 tune from CA Automotive. This Dyno is obviously set to read high as they are not making 538 whp, impossible. The dyno is corrected but we have no idea just how high the correction factor is. The gains are claimed on 93 octane but we just don't find these numbers possible without huge correction factors to exaggerate the gains on what is a notoriously low reading dyno.

      Before dyno:



      After:



      CA automotive says there are no tricks or exagerrated correction factors here, but clearly, that is exactly what they are doing:

      Here is what a modified M5 really looks like on a dyno dynamics, this one with aftermarket exhaust:



      The gains here are exaggerated and not an accurate representation.

        No worries.

        Can you please send me your contact details so we can start with this.

        I did some stuff for the UK forums and it's educated people so much that the majority now know how to read a dyno gaph properly, they don't just concentrate on 'peak' figures, they can sniff out foul play quickly and ask good relevant questions.

        I would like to have the overall car modding enthusiast community to know everything about a dyno possible + more about what actually goes on with the tuning side of things so we can make everything transparent. There is so much to cover but if we do it in a structured way it will be invaluable for the world wide community. At the moment we do have info but it's scattered and in many cases very vague.
