The LT4 was finally ready to fire, and the crew double checked all the connections, hoses, fittings, and added some fuel. The calibration is from the GM Performance ECM with some adjustments made to accomodate the Drive Junky pulleys, exhaust, and custom air intake. We use HP Tuners software and worked with Mike Norris on the calibration to get the car in a driving state.
Initial drives we casual, as we datalogged the ECM and would beam it over to Norris for analysis. We’ve tuned many an LS, but this was LT4 #1, and we trust Mike to be a great resource on these kinds of projects.
