Are there not more sophisticated tuning boxes now though?
I know the old ones just fooled the MAF with a resistor basically but I'm sure I've read there are some better ones about? Not for HDi's for some reason but for other engines (like the 1.9 CDTi/JTD for example) tuning boxes seem popular and give good results. Obviously not as good as a proper dyno'd £400 remap but surely equal to a 'cheap' generic remap as all some of those do is increase rail pressure basically?
