Best 6.0L service tech, central CA coast?

Following my other thread about my turbocharger that was replaced unnecessarily and then had the air & fuel filters replaced. Engine still acts slightly erratic at freeway speeds and has somewhat diminished power. No codes showing! I just don't think the dealer tech is ready for this one, and I don't want to pay them again for another costly wrong diagnosis. My regular mechanic suggests I take it to Diesel Injector Service in Santa Maria, CA, 70 miles away. Apparently they really know their stuff. Any other central coast recommendations? This thing needs a deep analysis.

When I was in Ventura, I used both of the below with great results.

Tarango's Auto Diesel Repair
1480 Harvard Blvd, Santa Paula, CA
805 933-3199

Ultimate Truck Performance
5651 Perkins Rd. Oxnard, CA
805 309-9900

Tarango's is a bit more old school, and Ultimate Truck is more current on the latest and greatest for diesel rigs. I'd be comfortable with either.

UPDATE:

It's been a while, and the problem had been consistent and slowly growing for months. The rig spent over a week at Tarango's in Santa Paula, and I took it home today, running fine (so far!). Hector, the owner, really knows his stuff and discussed symptoms and possible causes at a depth I have not heard from anyone else. He has the Ford computer analytical software, which was able to read codes that my ScanGauge never saw. Some codes were coming from the transmission but it was a wiring problem causing that confusion (tranny is fine). He put in my spare FICM and flash programmed it. Codes indicated a fuel delivery problem and he eventually found a wire or two on the injector harness that were fraying. Replacing them did the trick. He measured fuel pressure and flow and it was fine (since the dealer had recently replaced the fuel filters only and sent me home saying all was well). He monitored boost and vacuum while driving under load and determined the vacuum booster was leaking, so a new one was installed. He traced additional vacuum leaks to small hoses that seemed to be chewed on by small critters. Some were behind the dash and he got in there and replaced them. Now my brakes work much better. The dealer probably would have replaced the entire injector harness and other stuff until they 'discovered' the problem, costing me thousands more than necessary. I really enjoyed working with Hector, and recommend him. He is a diesel specialist. Thanks for the tip, Herb!

Glad you finally got it all sorted out. Having dealers/mechanics just throw parts at a problem (on your dime) frustrates me beyond belief.


Thanks for also posting the resolutions. Too many instances where people ask for help and never post how their issues were fixed, or if they were fixed.

I was so looking forward to making this report! I just had to wait so long to make sure it was real.
