| An extra 8psi fuel pressure will make you run rich because the injector pulsewidth of the chip you have would be set for normal fuel pressures. I realise every zed will vary in fuel pressure but an extra 8psi sounds a bit much. Normally you would have to be running 0.5bar of boost to reach those fuel pressure levels. If you consider Ash (and most tuners) will set chips a bit on the rich side for a "one size fits all" tune (for safety), add the fact your have higher fuel pressure and you can't help but run rich. This is where the benefit of a "custom tune" shows up. It is tailored EXACTLY to your car rather than the "ballpark figures" you receive in an "off the shelf tune"
