Problem with losing power at 5,500 RPM's and above.

New APR chip, K&N filter and Bailey DV. Worked fine for firet 100 miles or so. Then Started lossing power at top of boost. APR says it is the main hose from the o sensor to the turbo collapsing. Need new stronger hose Part#06A133356J. Anyone out there!!!

Most of the chips switch to a rich A/F mixture > 5500 RPM to prevent predetonation problems.

This was reported and documented in Europe with a video camera as proof

Didn't know that Audi had a stronger hose to resolve this issue as it does not happen with the OEM chip.

In Europe they were working off two solutions, one involved inserting a spring into the hose between the MAF and the Turbo and the other was to replace the hose itself with a metal alternative. It was discussed to have a silicone version fabricated but it might have been too costly.
