Stock Fuel Pressure '04 Z06

[Edward D]

When calculating new injector size for a 2004 Corvette Z06, what fuel pressure should I use - 43.5 or 58.x?
Thanks,
DE

58psi is stock, but it's best to measure it

Thanks - so when I use the spreadsheet to get values for the 60# injectors I will use 58. We will measure it though to make sure - thanks for the tip!
