Looking for MG Service Shop in Seattle/Portland Area

[RonStelvio]

I have a '09 Stelvio that needs help with a snatchy throttle... snatchy to to point it's not rideable.  I was fine last year but not now.  I will need a tech that's familiar with PC3 (Power Commander 3).  The roller rocker update has been done.

Do any any of you have a MG proficient shop recommendation?  Independent is OK.

As I live in Olympia (South Puget Sound area), going to Seattle or Portland is ok.  I can trailer it as necessary.
 
I have been unable to get in contact with Jason Wallace of DenizenMoto.  I also tried to reach him through WildGuzzi.

  Have you considered just disconnecting the PC3 and see if that improves anything ?

PC3 doesn't work on a Stelvio, it should be a 5 or 6 with autotune, Tod over at Guzzi Tech has maps. Disconnect the PC. Check the play in your throttle cable & adjust it to almost no play. I used to set up PC5 & 6's for customers at the shops I worked at here in GA
There are Power Commander centers up there but most likely not a Guzzi dealer. Before you can tune the PC you have to disconect it & tune your bike 1st

Best option is to bin the PC 3 and install a Beetle map.
