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...
Today is the last day to take advantage of the Memorial Day sale!
This has been one of our best sales yet. All Accessports ordered through 5/26 have shipped, and more are going out today from yesterday’s orders.
If you’ve been waiting, now’s the time. Sale ends tonight.
I received my Trail edition Cali Raised rock sliders yesterday and installed the right away. Their shipping was really quick, even though they needed to build them to order. They came well packed and on a pallet, without any shipping damage. I'm happy with the way they look and how easy the...
The method that Cobb uses to flash the ecu leaves no evidence that the ecu was ever flashed. It does not add a flash count and can be returned to 100% stock.
Session 15: The bottleneck isn't always where people think it is.
A larger intake only helps if something downstream can actually use the additional airflow. At some point, another component becomes the restriction.
That restriction might be the throttle body inlet. It might be the...
For Memorial Day I’m running 10% off all Cobb Accessport + tuning bundles, and the discount is automatically applied and shown once you add it to your cart.
The bundle includes the Accessport along with either a reflash or custom calibration option depending on what you’re after. Available for...
Those that did receive the VF TB inlets were disappointed because none of them fit. Glad SXTH is releasing one, and I'll have a prototype and dyno results very soon.
I just tuned a truck a few weeks ago that was not a hybrid, and he had a CEL from the intake. Long term trims were ~23% before I scaled the intake. Once tuned it was not an issue.
Using a map that was otherwise stock but has the MAF scaling corrected would make the fuel trims smaller, but would not net more power than not tuning (the tuner in me would be happier that the fuel trims were dialed though).
Using a Cobb map would make similar power (but of course more than...
Off the shelf as in Cobb off the shelf? Or stock? Scaling the intake to correct the fuel trims will not make a big difference in final fueling but can affect calculated load, which is the y axis on the timing tables. If fuel trims are high, calculated load is slightly low, which could result in...
As promised, I posted my findings comparing popular intakes here.

2024 Tacoma Intake Comparison Testing – Stock Calibration vs Real-World Results
After much online discussion about intake performance on the new 2.4T Tacoma platform, I wanted to perform a controlled comparison between several popular intake systems using the same truck, same dyno, same fuel...
You need to make specific changes to the shift schedule on these trucks to get them to dyno properly. Let me know if you want me to set your current map up for dyno use.
