I support SG
I do have respect to any Tuning shop like SG ,APH.
I have no doubt of both tuner even if APH seem to have done a mistake while setting up the dyno as shown on the dyno sheet provided by Draper.
I have visited both shop and quickly stayed with SG.
After I learned about them and saw their work in the racing world , yeah I am positive that I did a good choice , is he the best ? until someone show me another shop , I have no reason of leaving !
Yeah i also got similar result that APH and SG got on Draper's G37 of course I want the best power but peak power isn't everything.
