Hi guys, After filtering through all the misfire related topics and find very few threads with actual resolutions I thought I'd start a new one. Basically my 09 FG G6e turbo started misfiring at WOT when at the strip the other night. 400rwkw running E85 to give an idea of mod level. The thing had done it before, when it did I took it back to the tuner where it got a service and retune and came out happy as. Has been running sweet for about 6 months now but the problem has returned and is far worse. Essentially when I am on hard boost it sounds like it has a very bad misfire and no power obviously. Originally it was just under WOT but on the way back from the track it got worse, occasionally misfiring while.cruising at 100kph and but the time I got home (100km later) struggling to idle without misfiring. With slight throttle it runs smooth as so I'm thinking it has to do with ignition as the extra voltage with slight throttle will help spark but as soon as any fuel or boost is dumped into the engine it misfires again. I am yet to talk to my tuner (will today) but will update this post, through to resolution so hopefully it can help out the next victim. Keen to here any ideas or similar stories. Cheers, Joel
