Hi to all, I recently around 4 weeks ago performed the EGR modification as well as the inlet manifold swirl removal along with servo motor disabling as shown on this website. The car runs very well in all aspects, smoother,more power and slightly cooler from 100 deg down to 85 deg. But I have noticed that it is using more diesel than before the mod, I was getting around 7L PER 100 KM before compared to 10.3 L PER 100 KM now, quite a significant difference nothing else has changed apart from new MAF when mod was done, so Im wondering has anyone else experienced this after doing this mod thanks.
