Cool! Again not trying to start a anything here. I have respect for Rpi and we both even use the same tuner (ESS) so I know they only work with the best.
I did find out that another vendor on this site (not Rpi) ran a stock dyno and then installed a tune with the full exhaust but did not disclose that they beast was running a custom file. They are claiming that all of the power came from the exhaust system
