It doesnt seem like it should be that difficult, if you have an LPR gauge and all the tools you need to tune your viking, you should be able to do it.
At the very least, its worth a try, if you think you might ruin something or cant figure it out, go ahead and send it in. At least that way you get to know your gun.
If you dont have a tool kit..forget it.
