looking to purchase a supercharged tundra

First post, lets see how this goes..


I'd like to get back into a tundra, and I found a 2014 supercharged(Sc) Platinum model with 60k miles, Sc was installed at 4k miles from the dealer(TRD/Magnuson 1900).

1.)What is everything that should be installed with a dealer TRD SC install?

I ran the vin and came back with the history report.

Only issue that i have found with the history of the truck started when the original purchaser(OP) put JBA shorty headers and borla exhuast on the truck. Engine check lights came on for p420 and p430, all gaskets were changed, flanges on the headers were re-milled, finally resulting in both headers being replaced with OEM exhaust manifolds.

2.)Are Exhaust gas temperature(EGT) relatively high on the Toyota Tune that the dealers install?

3.)Is it suggetsed to move away from the dealer tune?

4.)Is there a way to tell if the truck has a dealer tune or aftermarket?(I have a vague memory of reading something, that dealers would label something, maybe the ECU? with a sticker)

5.) what all would you look for when inspecting a used Sc Tundra?

Thanks in advance for all the information that so many have posted in the general supercharger thread. 800+ pages, my apologies if any of these questions have already been answered.

 

1. Supercharger, there will be a coolant tank, oversized air intake but it'll look factory, the injectors should be green and not tan, there will be an intercooler behind the grille that looks like an AC condenser essentially. There should be wiring run from the intercooler pump to the fusebox. Nothing will be particularly obvious, if it's running normally I wouldn't be worried about parts missing.

2. EGTs are probably lower than stock since the TRD tune runs very rich. EGTs in general on Tundras aren't usually a concern, albeit no one monitors them actively either.

3. Generally yes, the TRD tune has some oddities and most aftermarket tunes are reliable and will make more power and have more features and capabilities. With that said there's nothing inherently bad about the TRD tune, so your call.

4. There is no way to tell if the truck has a tune. It probably has the TRD tune, but there's no way to know for sure or if the tune has been changed to something else. If the original owner never tuned it, it most likely has the TRD tune.

5. Check the supercharger coolant level, it should be red coolant and the same the truck uses. The supercharger should have a "subtle" whine to it when you get on the throttle. It should be totally quiet otherwise. If you hear anything that sounds like sand bouncing around in the intake---usually at idle---it means the supercharger coupler is going out. It's a $20 part but can be a little annoying to replace, if you're handy at wrenching it's not a big deal. Those are really the only issues specific to that model of supercharger. The supercharged trucks are generally very reliable, and while that's a decent amount of miles being boosted it's nothing crazy or anything I would worry about.

As far as checking the rest of the truck in general, lots of threads on that. I would test all the switches and controls, cycle the truck into 4Hi and 4Lo (need to be in neutral to engage 4Lo) and make sure it shifts correctly. Check for rust, leaks, crawl around under it and see if there's anything that looks off. The Tundra is pretty easy and if nothing jumps out as being weird or broken or sounding or feeling off, I wouldn't hesitate to buy that truck.

 

^ What he said.

But I would add - get it tuned. You will be happier. The truck will be happier. Reach out to @snivilous or @JustDSM when you have purchased the truck; they are both excellent tuners.

On used vehicles, I’m always inclined to do services that should have been done, even if they actually have been done. Fluid exchanges, filters, plugs (SC usual uses a different plug but I’m not 100% on the TRD 1900), belt, tensioners, PCV, shocks, etc. Inspect it as best you can, road test it, etc. On my ‘21, the suspension was worn out but could have easily been overlooked. I was able to negotiate price down on it and diff/tcase service. I would have done them all regardless, but I saved the money I spent to do it myself with the upgraded parts I wanted. It’s at the mileage where suspension wears out but might not be worn out completely, if that makes sense.

Post some pics of the truck. A supercharged tundra is a hoot to own and drive!

 

Wow thanks for answering each question, and for the fast response. I'll definitely check on the parts you stated.

 

I'm going to look at the truck this weekend, if it turns into something that I purchase, I will post some pictures to the thread. Thanks for the advise on the tuners in the forum.

 

All good info! Plus get the transmission fluid changed at 60k. They say it is lifetime but it is not.

 

You're kinda playing with fire buying a used truck with the blower already installed.
Especially if you're buying from an individual.
DEFINITELY have it looked at by the dealer before laying down your money!!!

 

This isn't the truck I'm looking at purchasing, but the truck I am looking at, has this same red loom in the engine bay with a small box in the wiring.. It looks like a piggyback for the mass air flow meter. I was wondering if anyone else had this in thier supercharger setup, and if so, what does it do?

 

Wow, 11 year old truck and only 60k. Not unheard of but not common. That wire loom isn't stock. I would look to see were it goes to and why. As for the rest of the truck just check it and check it good. Most people with SC tend to run them. Some run them harder than others.

 

Could be Rutech SAIS bypass, similar to Hewitt bypass. Used to bypass the air injection pumps at startup. But the other end would go to the engine coolant sensor. Still not 100% on what it is. Look for block off plates off the exhaust manifold air pipe.

 

I'll look and see if I can find the block-off plate this weekend.

 

Heres a photo of the truck, thanks for answering the questions. I'm sure there will be more to come.

 

Should be able to to see a plate between the exhaust manifold and airtime.
