Just got the test results back from Cruzin Performance. They weren't bad at all for 108,000 miles. Flow tests before and after the Ultrasonic cleaning. Just thought I'd share it with you guys.

Comments
Tests performed at 0.700 specific gravity.
The cleaning and flow tests for 6 injectors was about $100 including shipping. It took about a week to turn them around. If nothing else, it's a little peace of mind for the S38 knowing that they are all even again.
