They did a good job on my '94 GMC Sierra 4.3L TBI injectors. Was less than $100.

Two tanks of gas, each with a 20-oz bottle of Techron Complete Fuel System Cleaner mixed-in.

Thanks for the leads. They say not to use off the shelf cleaners unless you've been using em since new as it will break up particles and end up in the injectors causing blockage. One case had a piece blow through the little filter screen! I'm rebuilding my 300,000mi tbi for it's first time, wanna go that extra step in cleaning, eh. Thanks!

You could go buy a flow matched pair of injectors instead. Even original factory injectors will vary up to 10% from each other so, on 61LB/HR injectors we're talking a range of 55 - 67LB/HR. Makes it difficult to dial them in, just saying
Something like this, YMMV.
