We filmed Episode 331 a month ago, which means for once we are actually ahead of schedule. lol. It’s weird to even type those words. Anyway, this one is about the 1998 GMC Sierra work truck that Joe and I put together last October in preparation for its debut for the annual SEMA Show. While the truck ran and drove into the show and looked great, it was far from really being finished and road-ready. Before we could have real fun behind the wheel we had to get the transmission tuning for the Gearstar Level IV 6L90 worked out.
That required a few hours of time spent with Jeff Harris of Mo’s Speed Shop in Dallas, Georgia. Jeff plugged his laptop into the OBDII port of the truck and was able to manipulate the tune so that the truck would shift properly so we could drive at more than 1/4 throttle. While we haven’t strapped the shop truck down to the dyno rollers to see how much power it makes, we did road test it and take it to our local 1/8 mile dragstrip to help donate toys for local kids who didn’t have much for Christmas. Hope you enjoy the video, our next one will be about prepping Blasphemi for Sick Week 2025.
