Hi Eleblanc, if you are interested, I found that if you raise factory boost until just before the factory fuel cutoff the ECU does give additional fuel! - enough to feel the difference and be reflected on dyno. Doesnt make as much of a difference as a chip, but is in the order of 10-12% more torque/power for not much work. I havent checked the effect on air temp sensor on power/fuel yet, thats the next thing. I dynoed it at 132kw in 4wd at the wheels. This is much higher than standard and the vehicle hasnt a single other modification (other than the EGR line blocked off). Really makes it more spritely.
