Sixto,
Dave/gsxr suggested that 0 boost at constant speed might be normal (
Wastegate actuator swap for OM602.962?). I asked originally because if I run vacuum straight to the wastegate actuator I see about 5-7 psi boost at 70 mph. I do see boost going up hills which goes in line with 300D-91's idea that there might be situations where boost is more efficient than changing the throttle position.
If the EDS is cutting boost at constant speed for fuel economy then I should be gratefully for the EDS. But if the difference in fuel economy is negligible I could definitely use more smiles/mile, then again who couldn't.
I think Junkman has the best idea. I just need to get a sail!
