About Diverter Valves...
My warranty is about up, so I was hoping that my diverter valves would go out in the next few weeks so that I could have them replaced under warranty since they tend to crap out often. I bought some new ones from EVO, and I think my dealer will put them in instead of the OEM parts. How do I know if my stock ones are on the brink? They don't make a noticeable honking sound. Will they throw a CEL? Any way to hasten the process??? lol

At about 2500 miles, my OEM DVs started making a honking noise at ~ 2500-3000 rpm while under partial throttle and initial boost. With the bad DVs, I never had a problem achieving full boost under WOT. The dealer replaced them with Baileys under warranty.

Did you buy the Bailey's or did they? Did they honk all the time, or just under certain conditions?

The honking would always occur with the right throttle position and rpm range. It took some practice to identify and reproduce the right conditions - something I wanted to do so I could show the dealer the problem. But when I took the car in they just took my word for it and never rode with me or drove the car before agreeing to replace the DVs. Talking with the Regional Service Manager first may have settled the issue though.

He agreed, and told the dealership to buy the Baileys and replace them under warranty.
Thanks Dock, I'll try your route next time. Although, the car is out of warranty in 3 months...

Well I decided yesterday to install the EVO diverter valves that I bought. Popped the hood, looked in, and found that I already have Baileys. Oops! I guess I should have looked before I bought new ones, but I just assumed the car was stock. It's actually a nice surprise! Problem solved!
