Opinion on fuel injectors cleaning shops?

I was looking at this place...

http://www.witchhunter.com/index.php4

They charge $17.00 per injector. Anyone ever used them?

Anyone recommend another shop?

thanks

P.s. I should have checked the subject for typos before saving...

No opinions, huh?

I guess I'll have to answer my own question...I sent them off to WitchHunter today.

No, an extra set for my ProJection 4. They should be 85 lb/hr.

I've been trying to find my "missing" HP and recently installed a Holley 830. It helped some (guess 30-50 HP), but I get the same result by increasing my fuel pressure by 25% on the TBI. So maybe I just need a good cleaning. WTH, I figure it can't hurt.

Re: Opinion on fuel injectors cleaning shops?

Just got my injectors back.
Witch Hunter had the 1 to 2 day turn around that their wqeb site promised.
The injectors are individually bagged and numbered (on the bags) so that I can tell which injector is which compared to the flow sheet provided.

I DID NOT get any prior-to-cleaning flow numbers and was origionally upset because that is one of their promised services, so that you can make a before and after comparison. When I sat down and read all of the documentation they provided I found a note that all 4 were stuck closed, so no pre-cleaning tests were possible.

All of the o-rings were replaced and the injectors look like new. The old o-rings were returned. The injecorts varied from 944 to 996 cc/min (90-95 lbs/hr)@20PSI after cleaning. A 6.5% difference that Witch Huner said is typical with this type of injector.

All in all I am pretty happy with the service, I expect I will use Witch Hunter again. I'll probably put these on my car this weekend and then send my other set in to be cleaned. Since they are working now I should get some before and after numbers this time.
