06 Silverado Crew Cab Build

OK, I got the first mod tune file installed last night. I installed the NP149 driveshaft over lunch break, since the 246 driveshaft is about an inch too long to fit. I pulled the actuator and installed a 3/4" long piece of PVC to lock the front axle and no fear of the actuator backing out...... if it ever would. I drove it around the neighborhood and all seems good to go. I'll get it out on a better drive later on and get a data log to send back to Blackbear. Maybe take a cruise down Woodward, because this truck is such an attention grabber haha!!!

I pulled the switch and the TCCM out, with the battery disconnected, reconnected everything and no more "Service 4WD" message anymore. Got the initial tune file from Blackbear, data logged it. They got back to me, I was running it on 87 Octane, they want a log of it on 91+ octane since it's a higher compression engine (LQ9 is 10:1). So once I run this tank down, I'll refill and log it again.
