Power Surges on 1.8T: Resolution
Took to the dealer today and the Tech found vaccuum hose loose to bypass valve causing engine to loose fuel pressure sporaticly. The ECU logged an overboost DTC which led him to the vaccuum hose.
Thanks for helping guys!

"Need help guys. I have a stock 2001 225TTQC, stock for now. When in any gear at WOT I get some loss of power at about 4500 RPM's. Then I get some of the power back at around 5200 RPM's. Before chip, new DV, and exhaust I want to figure out why this is happening. Mod's might cover up a problem in the future. I have a few thoughts:
1. Bad or sticking DV, however, I don't get any of the honking sounds.
2. MAF sensor, I've only got 17,000 miles on it.
3. Hosing from from turbo to intercoolers to intake have a leak.
As a newbie to turbo charged engines, I am limited in troubleshooting exprerience. How would I properly troubleshoot the above? Or could I potentionaly have a different problem?"
