Hey there mate my name is Aaron and i am in the process of opening the doors of my new business In Tune Performance and Engineering which will be located in Oconnor Western Australia and will be opening on approximately the 17th of this month. From my experience a fuel pressure and fuel flow test needs to be carried out and probably a replacement fuel pump upgrade will need to be carried out. I don't believe that there would be a tuning issue such as has been noted. Hyperdrive would not have let the vehicle leave with a knock reading of 122. Something else has happened since the vehicle was tuned there. If the vehicle needs a new fuel pump i would recommend an adjustable fuel pressure regulator be fitted at the same time (not a Malpassi) as the vehicle will need to be re-tuned once these mods have been done. I also agree with one of the other posts recommending that the boost be dropped to approximately 12 psi if you are still using the std intercooler otherwise 13 psi will be ok if you are running an aftermarket front mount. My business will be providing a full dyno tuning service and i specialise in Motec, Haltech, Microtech, Autronics, Power FC, and Xede as well as most other systems on the market. Feel free to call anytime for advice or service on 0414874824.
Good luck with your project.
