LPE doesn't provide any data with their LPE pump. If the values in the leading edge table reference current to the solenoid, than upping the values for the LPE if installed into an LT4 engine with the stock LT4 lobe seem to be the correct thing to do. If you installed the LPE BB in an LT1 car with an LT1 fuel lobe, the OEM table would command more current/duration vs just installing the LPE BB in an LT4 car and leaving the stock values.

Anyhow I appreciate the replies. I'm not arguing anything at all. I've never seen anyone discuss this topic before. So I'm not suggesting any of my points are absolute. They are just the comments to the best of my available knowledge and a little bit of theory. Thanks for discussing with me, Ted.
With the LPE pump you do not alter the table just multiply the Y Axis by the percent the pump volume is larger than the stock one which works out to about 30% if my memory serves me, so multiply by 1.3

If you use a larger lobe 32% for example then 1.62.
