Truck is being torn down again. Hopefully we can get the VCT issue sorted so we can have more fun with it in the future with an Rains Precision Motorsports e85 tune!

My wife was hanging out with me in the garage the other night, and she decided to try to figure out what the labels on some of my stuff meant. I thought they were pretty intuitive.

You don’t have to win every race to make a great one.

This C8 eRay is no joke—Procharged, water/meth injected, and a consistent 10.5-second car at Pueblo Motorsports Park.

At the time, my Durango was nothing crazy:
✅ Intake
✅ 108mm throttle body
✅ Catless mids
✅ 10% lower pulley
❌ No tune

We lined up at PPIR during Ascend Down to Earth, and the Durango actually held the lead for more than half the track before the eRay’s extra horsepower reeled me in right at the end.

Altitude changes everything, and this was a fun reminder that even a “simple” combo can surprise people.

Who do you think would’ve won if the Durango had already been tuned? 👀 Him. It’s still him. Haha

So easy, a colorblind guy can do it.

Ascend Down to Earth 2026! We had a great time with great friends.

I got to run the DIY Durango against this awesome SRT Jeep with a Procharged 426. Unfortunately, he destroyed his transfer case in the process.

I’m sure he’ll be back at it soon. We are going to work with him to get the new transfer case he needs and get him back on the road.

I called my shot…and somehow nailed it.

Before strapping the Durango Hellcat to the dyno, I predicted it would make 592whp.

After adding an ATI 10% lower pulley to the Kong 108mm throttle body, aFe intake, and super high flow midpipes, we loaded it up on the dyno at over 8,000ft density altitude.

Result?

592whp.

Not corrected. Not sea-level math. Real-world Colorado power.

The best part is we’re not done yet. The logs show there’s still more left with colder plugs, tighter plug gaps, and a proper tune from RPM Denver.

⚠️ I do NOT recommend running a lower pulley without tuning, especially at lower elevations where the engine will see significantly more airflow and load than we do here in Colorado.

Thanks to Under Pressure Performance for some local dyno time.

Next stop: plugs and tune from Rains Precision Motorsports and then back to the track.

Built on trust, tested in the real world.

I finally put the $400 Spool Performance ethanol tester up against the classic $15 tube tester.

The results were NOT what I expected.

One sample tested around E85 with the cheap tube tester… but the Spool tester said it was only 74% ethanol. That’s a massive difference if you’re tuning a performance vehicle around ethanol content.

The second sample came back at 69%, which was pretty much exactly what I expected.

So now I’ve got a question for you:

Would you rather trust a $15 tester or spend $400 for the digital one?

Drop a comment and let me know which one you’d use and why. 👇

$400 ethanol tester vs. the $15 Amazon special. 😅

I’ve tested E85 with the cheap graduated tubes for years, but after hearing enough people swear by the Spool Performance Handheld Ethanol Analyzer, I finally decided to see what the hype is about. Spool Performance

This thing uses a real sensor and Bluetooth app to give instant ethanol readings instead of the old water-and-shake method. Is it 26 times better than a test tube? We’re about to find out.

For anyone running boosted cars on ethanol, knowing whether you’re getting E60, E70, or true E85 can be the difference between making power and making expensive noises.

Have you used one of these before? Worth $400 or overkill?
