Same here, my truck misses the $0.99 diesel it was used to.

The VW TDI uses a similar reverse dome with a peak piston. It creates less "wall stick" and more evenly distributes the fuel.
The good thing about a lower CR is you can add more boost without excessive peak cylinder pressures.
Wonder what size nozzles they are using and when bigger ones will be available
