holly EFI anyone running
Is this easy to install and tune any thoughts.
Easy to install
for the most part, plug and play...
you will need to use aftermarket gauges or piggy back to the pcm to use the stock gauges
I prefer to use the Holley Digital Gauges with the exception of the Tach and Speedo
you will need a 3 wire lsx oil sensor(like from a vette) or an Autometer/Holley Sensor...
you will have to do some bypassing of VATS things and you will have to wire around the BCM to get the fuel pump/starter relay's to work....
