Pro-Charged 2021 TRD Pro Overland Build

Great — so just to be clear, the were able to do the tune? Are you driving around using the supercharger now?

"HP Tuners has my ECU and the engineers are working on getting my ECU flashed. ATI / Procharger is very excited, because by all indications tuning support for the 20-21 4runners is here. I am holding out on saying that tuning support is available until I receive a tuned ECU back."

This is my latest update. Procharger's engineers and HP Tuner's engineers said they can tune it, after much back and forth. They asked me to mail my ECU to them. They received it yesterday. So no I am not driving it, I will make a thread if this is successful detailing what I did to get support. What they say vs. what gets done are two different things. Stay tuned (pun intended)

I’m choosing to read between the lines on this one. Taking it as a yes, first one. No, no commercially available tune.

I come upon this conclusion based on the ill effects that would come from driving a vehicle after having added a supercharger, but no tune.

I hope that OP would not want to go through the wait (again) for a TRD Pro allocation.

Very Accurate. Starting the engine with no tune, kitted with the new injectors & spark plugs could very well send my engine to Toyota heaven.

Man, this is one of the most elaborate and detail oriented builds I've seen in any vehicle forum. Kudos, keep the updates coming! Subscribed not only for the updates but specifically news of tuning availability for '20+!

How is the switchpro/powertray/arb wiring working out with the battery relocation? I see you modified the tray a bit and have it mounted in reverse. I was kind of curious what I'd have to do with a power tray installed in the standard spot (but no arb dual at the moment)

I used to think there was a bunch of wasted space in front of the radiator and behind the grille. Now we know - it was meant for an intercooler [emoji6]

Thank you! Lots more to come!

What is required to run a winch with the intercooler? Or is that even needed with an after market bumper?

That's exactly what I was thinking!

The bumper options with a procharger setup are pretty limited. A lo pro bumper is about all you can run. I am running the C4 lo pro with the clearance cuts. ATI/Pro-charger offers a "winch compatible" intercooler setup that mounts differently. At the time of ordring the kit I did not plan on adding a winch, but now I am definitely adding a winch so depending on clearances of the dimensions of the winch and the bumper... I may be forced to order the winch compatible intercooler. We will see when the time comes.

Well, the 20-21' have a fuse bus on the positive battery terminal that makes things a little more tricky with the switchpro connections & battery relocation. Ultimately I used a kicker marine fuse bus with blue seas marine fuses to replace the bus at the terminal. The picture of the kicker fuse bus in my photos was a necessity. The flipped power tray needed to be cut a bit and drilled to fit my application but it had all the basic components needed to bolt it up.

Stock Limited grille will fit?

Thank you for your efforts on this. I’ve been waiting specifically on the pro charger kit for my 21 pro. If tuning was available, I’d already have this kit on my 4Runner. Following for sure!

Tuning support is hopefully right around the corner. We will know soon. I’ll keep this thread up to date.

My shop/mancave is out in Tigard and I live downtown in the Pearl, work in Oregon City... I am all over :roll: I'll hopefully have it out and about soon!

You're not kidding, you've all over the place. I used to live on the border of the Pearl and Slabtown, but I moved to the west burbs a few years ago. Let me know when it's running so I can come see it!

Update 10/9

UPDATE: HP Tuners still has the ECU, eta is still a little unclear but I am expecting to hear back on Monday or Tuesday regarding the status of the tune.

I think I have decided on the 3.5 Long Travel Total Chaos Kit. Going back and forth between having coil-overs built for me or ordering the kings set up. We will see on that.

I finished up the Victory 4x4 Rock sliders. They don't fit quite as nicely as I would hope. the tolerances are a little off giving uneven gaps but its close enough to where I don't think it will be noticeable to anyone but me. I am half way done wiring up the led lights located in the rock sliders to the switch pro. I removed the TRD Pro roof basket and it is available if someone is looking for one... DM for price and details.

I acquired a vinyl cutter! I made a vinyl instagram banner for my rear windows... color matched in lunar rock vinyl :bounce: I have some more cool accents coming... Excited to share them.

I have added some additional parts to the shelf waiting for install.

- ComeUp Seal Slim Gen2 Off-Road Winch - Synthetic Rope - Hawse Fairlead 9,500 lbs
- ARB bluetooth controller for the twin compressor
- 30" baja designs WIDE LED light bar for the c4 low pro bumper

I am expecting my c4 bumper and bumper cut trim pieces on 10/18. We will see if I can fit the winch in under the intercooler. :hiding: I think some modification of the intercooler mounting and the c4 bumper may be unavoidable, but we will see!

Still waiting for the Victory 4x4 strike rear bumper, & Modified ARB roof rack

order custom anodized kings and get the right spring rate and valving to account for the extra weight up front while youre at it.



fyi the anodize and spring colors never match right, black springs are safe.

Order Update

SCS Gen 5 wheels 17x8 -38 offset wheels in black are on the way. Was able to secure a set of 5 from a new pal on instagram. Set of 5 on the way!

Ordered a set of 35x12.5 Nitto Trail Grapplers to go on the wheels

Total Chaos BMC plates

Ordered ADV Fiberglass fenders...

Hopefully will have some word on the LT set up this week. The build is coming together... Hopefully by December 1 everything will at least be on order. The last big piece to arrive is almost certainly going to be the coilovers and shocks for the LT setup.

Bumpers are expected within a week or two... I am so ready to get this beast on the road and then immediately find a place to get it off the road and in the mud :banana:

My mind is blown that a 12.5” wide tire will fit a rim size of 7.5”-11.5” wide. But if you’re good you’re good!

Just thought of something. What will be the result of a company who doesn’t sell superchargers tuning your ECU? Will we have to buy the Magnuson part and buy the tune from HPT?

I think there is some misunderstanding. The process for tuning the ECU requires a device to pull the "stock tune" file off the ECU. That file is then sent to the tuner (in my case it is Procharger) and then the ECU is re-flashed with the same device with a modified file embedded with the new values for the tune.

HP Tuner makes the devices used to pull or read the stock tune file. I sent my ECU to them so they could pull that file and then send it to Procharger. They offer Tuning support (ability to read and reflash ECU's) not the tunes or maps themselves.

Magnusson had /has their own tool that accomplishes this task, but you are still required to send the file to Magnusson have their tuners edit it and then they send it back to you. I believe they are using HP Tuners tool now, but I may be incorrect about that.

All of this to say... HP Tuners were not successful in pulling that file. The next step for tuning for my build is on hold until a TSB is released from Toyota for the ECU, which will give tuners a door into reading and re-flashing ECU.
