Hey Bruce,
I just sent my injectors to RC Engineering in Torrance Ca. They clean, bench test and calibrate all the injectors so they are all equal and give you a report. They even replace the upper and lower O-rings. Takes about 1 day. Cost was about $270.00 + shipping.
My engine ran a bunch smoother after I got it done.

Make sure you tell them that you are a paid club member.

I'm going to say the "calibration" part is misleading. At least by their page here:
Fuel Injector Cleaning
Looks like it is a flow/clean/flow sequence. If you have a factory Viper injector that needs a change in flow to match others, then IMO you have a bad injector, not a dirty one.
My procedure is flow/clean/flow. I do the work .... "I" means me, not some hourly paid person. That person somewhere else may really care about the service they give you, I can promise that it is not possible for them to care more than me.
If you by chance had a bad injector, I have spares sitting here.
I usually inspect the o-rings..... if needed, I have lowers and suggest if you need uppers or just want to go back with new ones that you order them from Chuck Tator/ Viper Wizard.
I'll also add, if you are having troubles...injectors or not....I can help you trouble shoot your Viper
Oh yea, for Viper guys it is $120 for the complete set plus shipping.
Plus, I just renewed my VCA banner earlier today
