C7 LT1 uses a different High pressure pump compared to the Z06 LT4. I have not had the chance to mess with the High pressure pump settings in tune. What I have learn that over 600rwhp is possible on the factory fuel system (93 octane) without Meth as a secondary fuel source playing with the SOI and EOI tables targeting a mid 12 AFR.
The LT1's pump FACTORY flows 2176 PSI, but in the tune has a HP PUMP MAX of 3118 PSI
The LT4's pump FACTORY flow 2901 PSI, but in the tune has a HP PUMP MAX of 3989 PSI
HP PUMP MAX limit is 4641 PSI by default
My question is has anyone just increased the pressure capacity of the LT1 pump to LT4 pump levels in the tune and tried this for increase fuel capacity?
