peak-n-holds

[Mike Pitts]

Has anyone ever taken fuel delivery measurement differences 
between peak-n-hold and saturated drivers, for the same 
injector at the same PW and fuel pressure? 

My thinking is that the P-n-H drivers may open the injector 
a little quicker, therefore delivering slightly more fuel 
for a given PW.  

Just want to know ahead of time if the fueling is gonna 
change when I upgrade my ECM.

Thanks,
