Hey viator, keen to share the name of the new tuner? I will need a good one in the next few months
As for Allstar.. LoL
My friend had a simular problem with them. Turns out they can not diagnose a mechanical problem for sh1t! They tuned my friends gtst with T04 turbo, Haltech ecu, custom plenum, bigger injectors, bigger exhaust (n a few more mods) and said that it was produducing about 160kw (from what i can recall) at the rear wheels.
Him n his mechanic knew there was something not right about this, because you can get more power from a stock r33 engine. It turns out that they did not know what was wrong with then engine, but still tried to tune it. The issue was, the teeth on the camshaft that connects the camgears was warn and made the camgears slip. A good mechanic/tuner would have been able to diagnose this.
After getting the camgear issue sorted out and getting it tuned by a propper tuner, the car produced around 400HP
Its good to hear that your car is being looked after by someone who knows what thye are doing!
