[QUOTE="superpsd, post: 1399525, member: 15821"] I think if 200% nozzles were so poor at atomization they would not run well on stock calibration. My tune for 200% nozzles has idle mapping areas that are unchanged from a stock program. If you toggle from my tune to a stock AA calibration it's seemlesss and idles purfect. The other side of it is pressure drop behind the Intensifier piston. An A code 6.0mm plunger has to stroke further to inject the same amount of fuel than a 7.1mm B code or Hydrid plunger will have to stroke. One reason why the large A codes are so oil hungry and you don't see any talk about huge A codes with 200% nozzles much. I have my daily tune for 200% nozzles set to 1.8ms and max of 3000 ICP. Drives and idles very nice. Only issue I have is the touchy pedal due to ICP rate. I may play with it more to tackle a happy medium as I finish all the other upgrades. [/QUOTE]
