CAMTuning's 2025 TRD Off Road Performance & ECU tuning build

[Pappy]

I'm continuing to tune local trucks and have an MT truck scheduled Monday, so watch out for those dyno #'s!

This was my truck. Cam came over to the house on Saturday after a club breakfast, and did a minor tune on my truck. Today, he did his dyno tune. I was pleased after the minor tune he did on Saturday. I was super impressed driving home this afternoon after the dyno tune. I can't wait to get the truck on the road for another adventure.

So much fun hanging out. This was our first manual transmission truck and has really heavy larger tires so even the baseline on stock map was quite low but we woke it up!

The torque is the killer.

Offset crank and iron sleeves will help prevent explody.

Open deck is certainly a decision on Toyotas end. They probably found with the offset crank they didn't need to do semi closed.

Subarus FA20 in the 15-21 WRX is also open deck, and offset crank. They're good till like 400ft lb before the rods bend. The explosion prone EcoBoom 2.3 in the Ford Focus RS had a bad headgasket part factory but I doubt the open deck and straight crank setup helped.

Maybe I'll pick up a wrecked truck engine and find someone to closed deck it and I'll stud it.
These rods are factory forged, so as long as the hardware (rod bolts) is good, they should be strong.

There's like half a dozen other vehicles that have been using this platform for a few years too. If you only care about the bottom end it won't matter what it came from.

You make a great point. I will keep an eye out.

Is there a way to graph your stock baseline vs mine? Those 285/70's made a big difference.

It would not be a good comparison since it is an auto, but when we tune Zach's next week I will get stock numbers on his for you and plot vs yours.

It’s time for a long overdue update on the truck.

I’m just over 11,000 miles now, and the platform has come a long way since my last post in November.

Since then, I installed a custom high-flow catted downpipe and went back through the calibration. I also re-baselined the truck in its current configuration with the SXTH Element intake and intercooler and the rest of the supporting mods. Green=stock 91, blue=all mods+stock downpipe, red=custom catted downpipe from FAFRace.

As expected, gains are incremental at this stage. On 91 octane with the factory turbo, we’re realistically near the airflow ceiling. At this point it’s less about chasing peak numbers and more about improving how efficiently and consistently the system works:

• Smoother torque curve
• Quicker, more controlled boost response
• Better repeatability as temps climb
• Stronger midrange without artificial spikes

Every hardware change gets logged, validated, and adjusted properly. The truck continues to serve as my long-term development vehicle and my daily driver, which is intentional — real miles, real conditions, real data.

And for those wondering what’s next — the upgraded turbo is already in hand and ready to go on. The factory unit has shown us what it can do. Now it’s time to raise the ceiling.
