How? The very second I drove the car out of the workshop and put my foot down, the dash light up, then it coughed and spluttered. Since then, its doing it consistantly every time, and now the cough and splutter is surging and rocking back and forth. How did this not happen on your dyno? Or how did it go unnoticed? Not hard to jump in the car and come for a drive, damn thing does it EVERY TIME. The battery is swapped to the other side, but it has since been wired in properly, strapped down, extra earth etc etc - another $400 down the drain to try fix the problem. A ford mechanic had a look at it, did some diagnostics and checks, all looked to be ok from what he was able to check at the time (granted he didnt go right over it with a fine toothed comb). Yes its an ex cop car, but I had none of these problems prior to the engine being replace / retune. I'd have sent the car back down to you, had I thought you wanted to look at it - the feeling I got was "It has problems, oh well" - and maybe that's not your fault and there's been a communication break down, but whats done is done. The quick run down of all this is, that the very second I got the car back, it was nothing like it should be. It only made 280kw, when the last time it was down there (with a sick half dead f*cked motor mind you) it made 310kw. It instantly ran like crap, the very first drive when I picked the car up, the dash light up and it coughed and spluttered - I dont understand how you missed this OR why the car was given back to me in such a poor state. As I've said, if Elite find a wiring problem and that was the case then fine, I'll just be glad someone actually found it. If its tune related then you'll hear from me.
