Looking forward to it Allen! May even make my way down to you guys from Frederick for a ProTune one of these days...

However, after last nights install (mods are in sig + stage 1+ aggressive maps) I have a strange whining noise that comes on above 11psi. It almost has the same tone as a supercharger pulley. Turbo spool is the only audible noise up until that boost pressure. I do not have any fault codes present and have not been able to get a log yet due to a late install.
