That torque number at the wheels is impressive. Are you still on the stock throttle body and airflow meter?

Yes to both. I think my MAF is maxed out.

If you decide to go further, the old TRD kit uses a massive air flow meter tube, it's somewhere around 98 - 102mm..... can't quite recall. There's also the 84mm throttle body from the second gen 2UR-GSE engine ( RC F, GS F, LC 500. More info if you want it.
Hot hot hot and watching the ACH work on the dyno is cool.
Nice work... this has me debating an LX build.....wife still misses the old 200. Great power - and nice to see ARH is supporting the 200..... I loved their headers on my C63..
Kooks did a nice job on the set they built for my 200 but I had an issue with the cat back they did rattling for a bit.....was a loose baffle I was told and we replaced the can with a Burns version.

BTW I ran a TRD intake on my 200 that was a hybrid of stock bottom from a Tundra and TRD part of the top as I recall - It flowed well whenwe dyno'ed it post headers , and clearanced the hood ( and also worked with the dorkle)...

So I do own the Magnuson airbox lid from the Tundra supercharger kit. I purchased it from superchargersonline.com. The lid fits on the airbox base just fine, and the 1/2 inch larger diameter of the hole is noticeable. The issue I had was the air pipe/coupler included with the Harrop kit wouldn't stretch over the larger hole on the Maggy lid. I even tried silicon spray lol. I never got around to sourcing a larger coupler. Also, about about the MAF sensor itself? Doesn't that have it's limitations?
I recall with had to get a silicon fitting for that..... Did they do anything custom for the tune or was it a flash ? Wondering if it could be tweaked to run E85....... I run 50/50 E and 93 in my car with a Eurocharged tune and it's good for another 30-50 hp...and runs cool ( mileage is horrible but.....) Jerry's houston based .....hmmm
Any mods planned for the suspension and brakes ?

Custom tune. I could probably have it tuned for e85 but I don't think HPTuners is as robust as ECUtek where you can have a flex fuel senor and adjustments on the fly, or at the least map switching.
No suspension mods planned, however I do have the DIY Tundra rotor/caliper upgrade for the front (354mm)

@RS6tofj80 So you managed to get the TRD supercharged airbox lid to work?
@boringdriver Yes, the afm can max out... however, the larger tube not only flows better, but allows the the afm to work in a completely different/higher air flow range before it maxes out.
The throttle body is also a big restriction. We bored out the stock 76mm unit to 80mm, and one guy gained 1/10 of a second in the 1/4 mile, no other changes. Mind you, that is with the TVS1900 TRD Kit. It has to hurting that monster TVS2650 even further.... These positive displacement pumps really dislike intake restriction.... tons of efficiency and flow to be gained there.

I feel like any more torque and I'll really test the limits of the transmission, so maybe I should stay put, haha!

I have been wondering about the TB restriction as well. TB Overbore is an inexpensive mod in general. Several of us 3FE owners did a 3mm overbore and got noticeable results. I don't remember how much we paid but remember is was not expensive. We had an extra TB that we did first so always had a core for the next person to send in to reduce down time. It looks like Maxbore gets 4mm on the 3UR-FE throttle body. I think the pricing is $150 with return shipping included.

I did the 3FE throttle body bore for my 2FE as well.

Awesome to see this, thanks for posting it up!
If you happen to know... how much tuning did they have to do? I've always wondered how well the new fuel pump, new injectors and stock fuel trim work together. Did they see any A/F ratios that were off? Or was it just dial it in/optimizing?
I'm on a 2020 so it will have to be a Unichip for me. But that is what the TRD kits came with. So Harrop+Unichip and a Unichip shop near me with an all wheel dyno. Hopefully next fall.

2007+ Tundra TRD kits had the ECU reflashed by the dealer.

Oh, my mistake, I thought that they came with Unichips. Maybe that was just a solution that Torfab worked out for the Nitrogear build to get around the reflash. Unichip advertises Magnusson support for the Lancruiser specifically and others have reported using it for Magnusson installs. Since I sort of doubt HPTuners will get around to my model year.

No worries! They don't flash anymore... the whole program was killed off years ago now... but the tune did exist.
