MY biggest complaint about Dyno2003 is that it doesn't seem to have any measurable difference between a hydraulic camshaft and a solid camshaft.
It's my understanding that any camshaft with lash adjustment has to be several degrees @.050 larger than a hydraulic equivalent to have the same timing at the valve, usually because the .050" measurement is taken at the cam follower (not the valve). This isn't reflected in the calculations and I consider it to be a BIG oversight.
