A dyno run for $400? I wouldnt bother in Newcastle to be honest.... DVS JEZ is one of our good members and a NSW EXEC, he also happens to own DVS Tuning which is handy as a large portion of our local members use him! Actually quite a few travel quite a distance to see him! Either send DVS JEZ a PM or add him on Facebook and send him a message, great guy and always willing to help, he is very very busy due to demand but will always get back to you.
Remember that Newcastle cops are cracking down on anything import or related and will hassle you for noise... So try keep it close to the legal db if you can to avoid hassle.
