How long is he down? Seems to me that a death should only take about a week's worth of production time.

Are you in that bad of a hurry? If so, you might as well go buy your own 3M injector cleaning kit at a local performance parts store. You can visually see if one is shooting more than another by putting each injector in a different clear glass and activating them. This can be done while all 8 are mounted to the rail. Attach the 3M cleaner canister which is pressurized @ 35psi and have at it. All you'll need is power. Find out how much juice is on your injecto installed and mimic it.

It'll cost you about $400 for the kit, but each canister is only $25 thereafter. Most folks just attach that to the fuel rail via Schraeder valve with the pump fuse pulled and let the engine idle out.

Wow,didnt know that...Hope everythings Ok for him and the people involved...

Ive used him before and I highly recommend Rich.
Youll get everything done,flow specs sheets before and after,etc.I had a set done by him and couldnt be more pleased.

Sorry cant recommend others because I didnt have a need to use anyone else.I recently recommended a family member to use him for injector service he needed done and never heard of any problems using rich.

I'd recommend Rich above anyone... but if you can't wait:

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

The person who runs that business is also on this forum occasionally.

Before I knew about Rich, I used TPIS. They charge a lot more than Rich does.
