Quick update on this 4Runner: The owner received his FaF Race high-flow catted downpipe, installed it himself, and found visible damage to the factory catalyst during removal. After the new downpipe was installed, we reviewed the data and made the final calibration changes for the new...

Session 17: What I've Learned After Tuning Triple-Digit 4th Gen Tacomas and 6th Gen 4Runners It has been a while since I have put together a Tuning Fact post, and at this point there is enough real-world data to step back and summarize some of the biggest lessons from this platform. These...

While most customers are looking for more responsive throttle, custom tuning can allow me to tailor throttle response and torque request for all modes to the owner's preference.

With gas prices where they are, I’ve had several existing customers reach back out about adding an 87-octane map so they can safely run lower octane and save some money on fuel. If I’ve already custom tuned your truck on premium, this is usually a simple add-on. It gives you a properly...

From what I've seen on our dyno, the factory catback is not a limiterat bolt on power level. I have dyno'd with the stock muffler, AWE, Carven (Probably the highest flow) and flowmaster. This is typical on modern 4 cylinder turbo engines. In the Subaru market, it's no problem to make 400+whp on...

I see. They don't have plans to update their off the shelf mapping. Custom mapping can make a huge difference, and you can have it tailored to your preferences.

I have been tuning a lot of hybrid 4Runners. What updates are you specifically looking for? All of the features that are required for a comprehensive calibration are currently available. The only thing we are waiting for is the approval from CARB so we can tune in CA.

I’m posting this in the non-hybrid tuning section because that is where most of my development began, although CAMTuning now supports non-hybrid, hybrid, and SR applications. There have been a lot of new members here since last fall, so I thought it was a good time to reintroduce myself and...

silver lining for sure!

Good timing. I've been looking hard at some lighting for my Tacoma and Tundra

you're not wrong, and that's where the sequence of events is a bit hazy. Regardless, the customer claims that fuse was indeed blown, and it coincided with the poor running and eventual stalling of the 4runner.

That's still an unknown. I considered the possibility that the entire add a fuse came out of the socket, but the customer says that it did not. I agree that it "should" have been fine. Since this customer is hundreds of miles away, I am sure there are some details that haven't been shared with...

Cool old Cressida. I bet that thing is still out there somewhere running.

I wanted to share a recent situation because it is a good reminder that aftermarket accessories can sometimes cause damage far beyond the accessory itself. This is not meant to call out the customer or the manufacturer of the grille lights, and I have his permission to share the story. The goal...

I've had them on my truck for a while now, but haven't been back on the dyno yet. I just put a larger turbo on, so I won't have a good comparison. In all honesty, I don't expect there to be any meaningful gains from the charge pipes. It's a popular modification on a lot of platforms, but more...

Too many EJ's meet that fate.

Subaru Brother! We still have 4 of them, ranging from 330-1000whp. My kids all drive turbo Subarus. I've been modding them since 2006, but now I have a 2025 Tacoma and 2022 Tundra.

Session 16: Air Leaks, Fueling, and Why Leak Testing Matters As more people install intakes, charge pipes, intercoolers, throttle body pipes, and other airflow-related parts, air leaks are becoming more common. The important thing to understand is that not all air leaks act the same. Where the...
