Sprint Booster vs Engine Tunes

[aggrobot]

Thanks aggrobot for your reply.

A few questions for you.

What is a OTT tune? Is it’s the name of a particular tune or type of tune? I’m aware there are several types of tunes but my knowledge in this area is still limited.

Is the only thing you did was do a tune?
Did you have to add anything mechanically to do this?
Also, are there any drawbacks?

As I mentioned earlier, I’d like to have a on and off button feature. I’m fine with the engine how it is most of the time but I do wish can push a button and have a little extra power when passing or going up hill.

Oh and I have a 2016 TRD Pro

Overland Tailor Tuning. I reached out to them via their website, and they put me in touch with a local tuner. No mechanical changes/mods/. The tuning process required the guy to have the vehicle battery plugged in to avoid any power interruptions during the process. Everything he used/plugged in was removed after he was finished.

ive not encountered any drawbacks so far. Its more exciting to drive, so I drive it a little more aggressively. Too soon to tell on MPGs but it hasnt been a bad drop, either.

Im not sure an on/off mechanism would be feasible given my understanding of how this all works. You may want to reach out to a tuner of your interest to find out what they’d suggest.

Thanks Aggbot. Thanks for answering my questions. I saw that Overland Tailor Tuning was mentioned earlier I just didn’t put the two together.

My impression from what I’ve read so far was that tuning gave you a little more power and pep but the drawback where it produced a little bit more carbon and maybe a reduction in mpg. That’s why I was wondering if there is a on/off switch option. As I mentioned earlier my Isuzu Trooper came with this function. So I was wondering if tunes for the 4Runner also came with this option too.

I also didn’t realize that tunes increase pedal response like Boost Commander. I thought they just increased engine power and change gear shifting.

Anyway I’ll call OTT and ask them more about their tunes.

Thanks again for your help.

No problem! I think its probably worth noting that I dont know for certain that my MPGs were impacted negatively. Ive been driving it quite a bit more aggressively and my MPGs havent changed all that much YET. This suggests to me MPG may have actually gotten a lot better, not worse, but only time will tell.

the biggest difference we noticed was it drives better on the highway. itll hold 70-80 much easier than before. it stays in a gear and cruises. heavy 33's and a roof rack dont help

that and the more aggressive shifting.

Without the super charger engine tune wouldn't do much. Adding a bigger maf and remapping the fuel map and throttle curves on a stock engine dont' do much. Adjusting the VVTI timing can give you more torque low and mid rpm at the cost of less fuel efficiency and and VVTI gear wear.

Do you have any more info regarding VVTI gear wear? Id like to learn more about this, and expected wear vs accelerated wear, etc. Ive not heard of this being a challenge in the past, but it certainly sounds like something worth knowing more about.

Did you get an improvement in MPG? Im on some p-rated 285s, lifted around 2.5 inches, and look to be averaging 16-17MPG at the moment. Lots more data to gather here, but pretty encouraged with what im finding so far.

from reading taco forums about kdmax tune there should be a slight increase in mpg with it running a tad leaner

Yeah, it makes good sense. Just wondering as he has the vivid tune and I’ve gone the the OTT route. It’s been a very pleasant surprise to see an MPG improvement. It’s worth nothing that most of that improvement has been seen in highway driving. More driving to do…

Some insight on what throttle controllers actually do. Throttle Controllers – A Guy A Girl and A Trail

For those wondering about the OTT tune and what it impacts, I can share my experience as well. I’m in a ‘22 ORP, with heavy E load 285s, a roof rack, aluminum armor and 2 inches of lift.

With this tune, I was able to choose between a stock/mild, medium and aggressive throttle response. I went with the medium throttle response since I’m not loaded down with steel armor, an RTT and the like. I’m actually debating down to the milder throttle response as when I’m unloaded it can break the tires loose in rain or snow unless you’re super careful.

I think this comes down to having a bit more torque down low with the tune, but the best part of the tune by far is being able to used my cruise control again! I can cruise at 75mph and it holds 5th unless there is a moderate grade, whereas I would spend a lot of time in 4th previously driving the same roads or it would hunt between the two a ton which was frustrating.

I didn’t see any gains in fuel mileage, but it didn’t get worse either.

One thing to consider with a tune and changing your throttle response vs a throttle controller is that it can’t be adjusted on the fly, so if you use 4LO off road, it can seem to sensitive when you may not want it.

Hope this is helpful!
