yeah thats fine was just wondering, yeah nsw, got mine tuned by Mark at MRC performance in castle hill. i was VERY happy with my results after a shit tune by someone else aswell. mine was pinging, running really rich and missifring. Now is fine, running like it should.
As to your question about if it could be anything other than a bad tune, mine was doing the same as yours, my 2 main problems were my iridium plugs were shit, so dropped some coppers in with .7 gap and my bov was blocked off, i didnt know about this as it was a gasket where the bov bolts onto the intake pipe. After this was pulled out and given the flick the car ran 10x better.
