GT3 boost problem

Recommended Posts

Posting hard today.

Just got my GT3 back after a few years in storage and guess what? It drives like a dog.

The boost gauge registers boost building pretty early and build to a maximum of 0.5-0.75 bar (hard to tell but could be 0.65!) but the engine feels absolutey gutless and with lag of about 3-4 seconds, very poor throttle response and very underwhelming boost when it does kick in.

Waste gate capsule was replace before but the symptoms where different. That time I had almost no boost at all until 3500 rpm and then it was great.

I am thinking a poorly adjusted wastegate or TPS sensor may be good places to start. Any other thoughts?
