My gut reaction is that it looks pretty slow, I would expect a health cam/gear setup to gain nearly a second over what it was capable with as a bolt on car, but that can vary some.

I suspect there are some issues with your mail order tune as well. Your launch sounds suspiciously like it's probably riding the RPM vs. MPH limiter - from the factory these cars have a table that limits the RPM to 5000rpm until the vehicle is moving over 10mph. This can make launching a stick car on a good track with a good tire tricky - you need more RPM than that unless you're coming off a two-step. I have a good quick video about this on my YouTube that might apply here.



I also have a lengthy video on launch techniques for these heavy M6 cars. You might find this valuable as well.

great info here!
