Since we are currently doing calibration development on the dyno; we would gladly incorporate your header testing with the work we are already doing at no cost.
Yes you are welcome to make the hardware changes yourself to help control costs.
If you would like to make a donation for fuel and the development of an engineering report of the dyno data; we would, of course, welcome that.
We are interested in your project and helping your further your developnment if we can. We continue to look for ways to participate in morotsports projects. If we can provide you with meaningful development data, we hope you will tell your industry friends about our services.
