I had the trifecta tune on my Colorado as well. It was a ext cab work truck though so it was really light. It did 14.08@95 in the 1/4. It would shift up and just sit at 95mph speed limiter for a 150ft. lol. if I kept it it would have been lowered with larger dia wheels and higher speed rated tires so I could raise the speed limiter.

At the track I used to launch in 4h and switch to 2h just at 1st gear. Also surprised a lot of people with how quick it was. Lol

Yeah the tune changed that shifting a lot. Stock it would short shift well before redline guessing to keep it more in the torque band. With the tune it would ride out every gear to redline. Plus the work truck models have skinnier 16” wheels and tires which were also a little smaller diameter than the other trims. the DA on the day I ran it was excellent cool fall day. Slowest was I think a 14.8 in 2wd and could not launch it at all. I basically focused on the 60’ all day. I removed every damn thing I could too. No spare, no jack, 1/4 tank of gas plus I weigh a scant 130 lbs.

14.doh dammnnnn! Truck feels to me like it could run 14s.

How much is the Trifecta? Does gas mileage suffer?
I didn’t notice a difference in mileage. Not sure on the cost though. They have a nice interface and software. Ohh if you are really adventurous HP tuners will work on the truck too for tuning and logging. I did a full read on mine but never did anything with it. I logged it once in a while for fun. Lol.

Funny story, I was leaving Midway airport last night and I saw a white 1st gen Colorado and a newer Silverado on big tires racing from light to light. I obnoxiously weaved my way through traffic and was able to line up with both of them, 3 lanes wide. I didn't brake torque the ZR2, just launched off idle. I came in second behind the older Colorado which did not sound stock. I have come across a 2nd gen Colorado guy who went 14.1 with a tune, and my buttometer tells me this truck is somewhere in the 14s. Fun times.

Now I want to tune it hehe.
