I don't think you can really tune a CRD much by default, at least to my knowledge. I know Mark from JPC spoke to me about tuning the MAF. Something about a diode and voltage tinkering to better "tune" air/fuel ratios... I don't know what purpose though, I can't remember.
My chip was tuned to my car with exhaust from scratch. Brand is Unichip. Heres the dyno results below before and after. I also got them to fit up a wastegate to the turbo and tune it to that. He got much more out of it, but backed it off a little. The car was a completely different beast afterwards.
Wow that's a massive increase,much better to drive as well i cld imagine! Do you mind if I askhow much that set up cost you? I have heard really good things about the unichips compared to other brands
