A downshift at highway speeds with added throttle input isn’t necessarily a bad thing — especially on a small displacement turbo 4-cylinder. In many cases, it’s actually preferred. If the transmission stays in a tall gear and you roll into the throttle, the engine can lug at low RPM while...

I can help it hold boost by demanding torque at lower throttle and higher rpm. The stock mapping does just what you mention, although there are a lot of layers to how torque and load are managed in these vehicles.

Part of that is torque demand, but a lot of it is TCM mapping. By tuning the transmission to be in the right gear at the right rpm and throttle input, it can keep the engine in a more responsive range. This is one of the best benefits of tuning. I am less concerned with full throttle power and...

I've had the opportunity to road tune quite a few trucks, and follow up with dyno time (just did another this week) and the difference is negligible.

There’s been a lot of discussion around first-gear load limits on the T24A platform, so here’s a clear update. This applies to the hybrid as well Earlier calibrations had a defined load ceiling in 1st gear. That meant even if boost targets were raised in higher gears, the ECU would limit...

Session 8: Pulling these concepts together, and what to monitor on your Cobb Accessport If you’re running a tuned 4th Gen Tacoma / T24 truck, your dash should give you context, not anxiety. Here’s the clean setup I recommend: 1. KCLV (Knock Correction Learn Value) This is your long-term knock...

yes that comfort is intentional slip. With tuning have full control of shift behavior for each gear, and each mode (normal, sport)

Toyota doesn’t publish a hard “max torque input” number for the AL80F, and anyone quoting a specific figure is guessing. In the real world, it’s less about a single torque number and more about heat, shift management, and how the torque is delivered. Smooth, controlled torque is what keeps them...

I’m not seeing the stock fuel system as a limitation so far—even pushing higher ethanol blends. I’ve run up to ~E55 on my own truck without any fueling issues in the logs. That said, we’ll confirm the real ceiling through continued development on the stock turbo, and then on larger turbos (we...

Totally possible! I did some testing on my truck on E30 and the gains were substantial! Stock 91 vs tuned on E30 (intake and intercooler)

I understand why this feels true, especially when you’re watching real-time MPG numbers. But a few things are getting mixed together. Modern fuel-injected vehicles are designed and calibrated around E10. Fuel trims, knock control, cold starts—all of it assumes some ethanol is present. When you...

Boost tubes won’t be a significant, driver-detectable improvement, especially once you factor in an intake and a proper tune. They mostly shift throttle signal behavior and don’t change torque management or transmission logic, so real-world gains are minimal. I’m with you on being old school —...

Day late this time around. Just spent the last several days with the Cobb crew at the King of the Hammers. I've never been to that event but it's something you have to experience to understand! Easy reading this week! Session 7: Throttle ≠ Power Not every throttle input needs full power. A...

I have not. I have a customer who’s a service manager at Toyota and he had to do a recall on his truck. He unmarried the AP, connected their software, and sent me screenshots confirming there was no record of a flash and the ecu presented as stock.

You don’t need the CAN connect cable again after initial install.

Session 6: Rotating Weight: Why Bigger Tires Feel Like Lost Power (and How Tuning Gets It Back) Let’s take a quick break from sensors, trims, and tables and talk about something you can feel immediately behind the wheel: rotating weight. Earlier this week I had a Tacoma on the dyno running...

That is the current sale price (Cobb' Authorized) through 1/29. All current COBB OTS maps (like Stage 1) are included, and if additional OTS maps are released later, you’ll have access to those through the AP. This does include transmission tuning. Where the real difference comes in is custom...

The Accessport is worth it on a daily. The biggest gains aren’t peak power — it’s smoother throttle, better torque delivery, and overall drivability. Every truck behaves a little differently, which is why custom tuning makes a noticeable difference even on mostly stock setups. Worth noting...

Gains are TBD- but should be considerable. 400+whp is going to be no issue. Factory internals- we will push Nick's truck to see what's possible, then offer a more reserved calibration for the general public. The 2JZ was a special kind of beast. That was a cast iron block with closed deck...

Last coupon used yesterday! Thanks everyone!
