Ok guys it's me again with my home user name, so this has been my experience so far with mods to my G6ET, the first tuner I went to promised me the world and delivered fark all, he said with injectors K&N and a custom tune I would get 300+rwkw, at this stage I thought a venom high flow cat would be a good idea as well so after these mods we ran it up on the dyno in Geelong and didn't get much over 240rwkw and boost was lagging until 3000rpm, suspected boost leak so I went and bought a Herrod piping kit, plasmaman throttle body pipe and a Cheap FG F6 intercooler, issues with power and boost still remained so the next step was to replace the waste gate actuator and port the waste gate to eliminate turbo bypass through waste gate, this also did not work so I then got jack of dealing with this *beep* and headed to Melbourne, this is where I gained my 289.5rwkw and this tuner is the one that told me my 750cc injectors were sh*t!! Sorry about the novel but this gives you an idea of my frustration, and I do apologise but I won't name the tuners
