      Boost seems way to high. Help!

      Help!

      Running Cobb Stage 1 Drive map. Drop in high flow air filter is the only other mod. Otherwise stock.

      3rd gear 2500 RPM to redline and 4th gear 2500 RPM to nearly redline. It was 69 degrees out and I am running about 95 oct at the moment. Typically would be 91 oct Arizona. I have attached the datalogs and graphs from virtual dyno software. It feels fairly slow to be honest but, I have higher boost levels than expected still. What can we make of this? I really do not want to destroy the engine. There were no negative timing corrections however so that looks good.


      Something to keep in mind. This car has new turbos and waste gates factory replaced. It has a new thermostat ( not sure that matters ), all new coils and all new spark plugs. It previously had a JB+ on it but was removed and car started and stop cycled prior to flashing with Cobb AP V3.
