@jpnovak - the injectors are 24 lb Bosch EV6 models I bought from Five-O Motorsports last fall. They provided a data sheet showing the flow rate at different pressures for each injector. They also provided dead time data from 7 through 18 volts. I've included the data below. I must admit that I've been a poor customer as I found the car didn't run as well with their dead times. Based on their data I should be using a dead time of about 0.51 ms at 13.2 volts, however, I'm using 0.9 ms as a dead time. Given what you noted about the rich running condition if the dead times are off I should generate a new tune based on the suggested values from Five-O. The injection pulse width I generally see the issue with is in the 1.9 to 2.2 ms range, In terms of injector squirts I'm using 2 squirts simultaneously per cycle and the injectors are wired 1/2/3 on one bank and 4/5/6 on the other.
