You can expect 140-150whp gain over stock with the appropriate exhaust and the maggy kit before needing fueling modifications on 93
The low side pressure drops which in turn shortens the range of the high pressure pump and injectors.

A JMS fuel system voltage booster easily extends the range past 700 RWHP.

My 2018 ZL1 and many many others make 670 RWHP on E-60 with the stock blower and I have been 725 on race gas with the LT4 fuel systems.

It is also important to achieve commanded Lambda which is .82 for me.

If you are .78 you will shorten up the range as well.
