Cheers guys - I agree with you about the GIAC situation... however I think it would be a losing battle fought at long distance... as I have no evidence to prove it was not right at the time I left Star Performance and the time and effort to get up and down the road would be considerable. My car was pulling with the REVO trial map on as well, but all was good apparently with the stock map... although Dave didn't record this, but the out put was what it should be so have no reason to doubt him.
Star Perf suggested changing the plugs [done] and the coil packs... which dave has said he would do for free for testing purposes.... so my next plan is to have some full data logging tomorrow lunch time at Tiple H Motorsport (REVO Dealer), purely becuase they are literally 5 mins away from work, and the if all is well head to PDT for a REVO stage 1.
So I will have wasted £466 but my plan when I bought the car in April was to have it mapped... as coming from a 350Z the stock Ed30 would have been too slow ;-)
