Diverter valve
Anyone know if the 710N is the correct diverter valve for the UrS4?
I believe the part number is 06A 145 710N.
I want to do some testing with a new valve against the Forge unit and i want to be sue I'm using the correct one. Dave? Thoughts?

Dave,
Thanks for the clarification on the valve PN. Looks like the DV is not my problem, pretty sure at this point we're looking at a boost leak somewhere in the system. C'est la vie. I'm going to pull the output hose on the turbo and pressure test the system tomorrow.
Damn. So much for a quick, easy fix.

I think I'm having a vacuum leak too. Its worse in low gears around town. I can get solid boost in 5th on the hwy, with med throttle.
I have to go easy on the trottle or it 'stutters'. Very similar to what my S4 did before I realized the vacuum hose was slipping off behind the black plastic guard on the firewall. I went into the CPU last weekend and made sure my hoses were secure on the moisture-trap and the CPU...still doing it.
I have the 3 silicon hoses, and recently installed a LS2 ignition kit, so I dont think thats my problem.
If I figure it out I'll pass on the info. Its driving me crazy.

If you got your LS2 kit from Marc S. at EFI Express, you should go back to him and explain your missing problems. There have been problems with some UrS cars and his kits. It is either the coil driver or there is a voltage issue, e.g. your alternator/regulator isn't putting out enough volts for the LS2 coils to work well. Contact Marc.

Yeah I checked all the plugs to see if any of them are loose today as well and traced all the hoses to see if there's anything obvious. There wasn't.
Hoping I can get into IA tomorrow for a diagnostic. I'd like to get that Forge DV back in as well, maybe after we find what's causing the issue.

It was indeed a boost leak. Car is running great. Alex tracked it all down in a couple hours. Alex also put in the ECU with the 24lb map. Car feels really good now. A Sunday well spent.
