I recently had a Saleen Supercharger installed on my 2008 Lincoln Navigator. I purchased the unit from Stage3Motorsports in AZ. I had a local Ford dealership do the physical install. Stage3Motorsports also provided a handheld SCT tuner with "supposedly" the correct tune installed for my tire size, altitude, gear ratio, etc.
That was programmed into my PCM/ECM at the time of install.
The "tune" wasn't right and the engine 'surges' at idle when the AC is running. (It also has some other quircks as well.)
The new tunes that Stage3Motorsports has sent in the meantime haven't fixed them so I'm about to seek out a local tuner who can help.
Any ideas/ recommendations?
