got in a little tangle with a 6. 0 the other day on the highway... he was straight piped, and I'm guessing he had a box or chip of some sort because it was blowing smoke, and he had a little digital readout box on the dash near the driver's a-pillar...
put a few trucks on him in 4th from ~60-75... I let out and waved as he came by... we turned onto another highway, and he nailed it getting on... I had it in 5th at ~60, saw him go, and I rugged it... took a second for the smoke to clear and for my truck to start moving, but we were both in the left lane standing on it. I came from about 10 lengths back to knockin' on his back door pretty hard I went ahead and got out of it vs. ramming his rear bumper!
good times
