Got to go on the first drive today since we flashed the speed density tune. No crazy raging on it or smokey burnouts yet. Just cruising and slight throttle increases to make sure everything is happy now that we've switched it all and verifying all the air fuel ratios are good. After some research i've discovered I need to wire in a 1k ohm resistor in order for the aftermarket tach to function properly with the factory LS tach output. so I should be doing that tomorrow.
I set the electronic boost controller up to basically open the wastegates anytime I got into the throttle bleeding off the excess gasses so it kept me out of boost(failsafe move to save me from myself)
