Default Professional Injector cleaning/flow testing- injectorexperts.com?

Hey All,
Haven't posted in a while- long story short my C5's been parked for over a year now Started taking it apart, then my project ADD took over, started finishing the kitchen, then the basement, then got a tractor (which needed work) grad school etc. Anyway, at 200k and a bunch of minor things wrong, first became- replace leaking steering rack and wobbling harmonic balancer to doing a complete block removal and refresh (new cam, lifters, pistons, etc etc), newly machined AI ported & polished heads, replacement of all sensors, headers, LS6 intake etc etc. I have the "How to Rebuilt LS Engines" book and it's been great.

One part mentions in the cleaning/prep chapter that fuel injectors should be professionally cleaned and flow tested.

My cam is a Stage 1 BT cam so I don't think I'm going to need new injectors (28# @ 4 bar for a 98 I believe), but I'll cross that bridge when I get there. The heads are AI ported and polished as well.

I did some searching and came across www.injectorexperts.com sounds like Keith Brewer- is the one man shop out of Risingsun Ohio. He charges $20 each injector, so figure around $160.

But what had me concerned, this YouTube video comments, people said he would take their injectors and disappear. However, He has an A+ rating on BBB

and there was an article by GM EFI live recently on him (this past Nov).
http://www.gm-efi.com/tech/injector-...oem-injectors/

I don't mind sending my stuff to one man shops I've found on the net - as I've done so on several other items (motorcycle brake discs, Cub Cadet tractor check valve rebuild), but I didn't see any reviews here.

I still have alot of work to do on the car, so it will be a few more months with the car off the road. Rebuilding the rear, and trans while I'm at it, so even if it takes 2 months for him to return my stuff it's fine with me.

Anybody deal with this guy, or have another source? The alternative is just to buy new injectors to begin with- but I won't know if that's needed until I dyno the car. And at that point, the last thing I want is to take the car off the road again Since the car is inoperable now, it's a great time to send them off, and I'm so far into this project now even "losing" $160 won't be too painful, should I need replacing them after dyno-tuning anyway.

I sent mine to New Era Performance in Rochester (think they are a sponsor). They did a great job, labeled each injector and then me a sheet to show how each flowed. I took the two highest flowing injectors (minor difference) and put them in the two rear cylinders with the highest in #7. Might want to give them a look here------>New Era Performance Injector Service

Excellent! NY isn't far and it's pretty reasonably priced.

Update- I used New Era Performance. They labeled each injector and as you mentioned gave the before and after. Some of them had 0 improvements and others had very little increase in flow. None of them were wildly off the mark though. They got them back to me in less than a week. Now, to start pre-assembling my block
