I've just upgraded from the OEM LT4 injectors to the XDI LT4 +30% injectors on my car that has an LT4 HPFP with a +32% fuel lobe cam and a DSX low side secondary pump.
The calibration sheet that came with the injectors shows the Flow Rate in HPT needing to be changed from 17.73g/s to 22.94g/s. This is based on the average flow rate tested across all 8 new injectors.
My question is: is this single change enough to be able to start and drive the car so that I can begin to get some log files for my tuner (if he replies to my emails!)?
