There isn't much a shop can do that you can't. Most places around Tampa haven't the slightest clue how to work on VR's (FI at that). If I were still in town, I'd have helped you out for free, just to see another VRt on the road. The only other guy I know of is in Temple Terrace. PM WilliamsVR6 on VWFixx and he may do something for you.
If mechanical timing is your issue, follow these rules:
- Keep chain slack on the tensioner side while cams are locked
- #1 piston at TDC
- Intermediate chain pulley should have a visible "half moon" or notch if looking down in engine... if you can see it, you're fine.
- Give the engine 4 dry turns with a wrench and without plugs. Your marks should all re-align if timed correctly.
If Ignition timing is your issue, then that is something you can't fix unless you've manipulated it with hardware/software combo. (MSD, EFI, Etc..) Otherwise, you'll have to send your chip back along with printed AFR's.
Just to keep it safe, drop in a 4bar FPR and run it on the dyno.
