The MT is definitely tuned in a way that forces the driver to upshift to get to the torque.
Best way to do that is to have the MT tune make less torque at low RPMs. The MT is definitely tuned in a way that forces the driver to upshift to get to the torque.
They didnt want people to floor it in 6th gear at 1700RPM at 60mph, cause you'll knock the thing apart. Lugging is probably one of the worst things you can do for a modern DI turbo engine (these have conventional injection as well). Lugging is impossible in the automatic, but very possible in the manual.
They don't want a repeat of the Corolla GR situation where people were romping on it in 6th gear at 70MPH and wondering why it was ejecting it's internals all over the freeway
MT 4G is an unusual case here, many other modern gas 4 cylinder engines paired to a MT make peak torque below 2000RPM.
Idiot proofing the MT 4G kind of negated all the gains from the long stroke setup, since peak torque is now 1000RPM higher, making the RPM range where you can make power pretty narrow. Lame choice by Toyota but I guess they didn't want to test the bottom end durability when someone leaves the truck in 6th at 65MPH and floors it going up a grade with a trailer
Yeah maybe he assumed LSPI would be too advanced of a term for the audience or something. Either way I think Toyota should have just uncorked the MT and let people figure out why their truck is making a terrible sound when they floor it at 65mph in 6th gear 🫨
Once Stage 3 is ready, you’ll need to upgrade from the Stage 1 OTT tune you already have. The hardware requires the calibration updates in Stage 3 to take advantage of the new flow potential.Will this work with the OTT tuneI have already?
On pump gas, the stock injectors have plenty of headroom to support the additional airflow. Where we expect to run into limits is with higher ethanol blends. OE injectors likely won’t have the capacity for that. We’ll confirm as testing continues.
450 wheel horsepower on the hybrid is probably a stretch, but with the electric assist factored in, I think this turbo could put you quite close to 450 at the crank. We’ll know more once the dyno data comes in — I like to keep the “virtual dyno” claims in check.
Thanks for the enthusiasm and support. We'll be sure to keep you guys posted!

That said, this upgrade directly addresses the “falls on its face after 3,000 RPM” feel. Even our Stage 1 calibration (tune only) already fixes a lot of that without requiring any hardware changes. It pulls much harder to redline than the factory calibration. If you haven’t tried Stage 1 yet, it might give you exactly what you’re looking for at a much lower cost of entry.

Give our Stage 1 calibration a try. We actually offer it in three variants, including one that keeps the factory throttle mapping completely stock, so you won’t get that “over-caffeinated” feel you experienced before.
Are you sure that is the correct gasket part number for the manifold-head? My parts catalogue has that as a gasket for a 90s Supra. The part number I get for the manifold gasket is 17173-25040. All other part numbers in red look correct.
Thank you for the catch! Not sure how that got mixed up. Will correct and update the image.
No worries! I just quoted one of those for a customer this week, so I thought the number looked familiar. So I did a quick check for what does go on a Tacoma.Thank you for the catch! Not sure how that got mixed up. Will correct and update the image.
