Best BUDGET Way To Tune YOUR YFZ!

We have had two 2020 YFZ450's, and like everyone else, we had the issue of them running lean. First we tried the Power Commander programmers, and aftermarket exhausts, nothing worked. Then we discovered Pep Performance Tuning, they can reprogram your stock ECU based on the mods your YFZ has to get it running perfect!

That is interesting & solid info. Why buy a new ECU /tuner etc. Thanks! Gonna look into this as I only want a new pipe /better flowing intake on my newer YFZ450. It's quick enuff! - Ohio

Thanks man, hope you enjoy it!

Awesome video and thanks to the great guys at PEP.

[@TeamWaxOffroad]

That’s right!

[@atvtrailing9401]

@teamwax off-road, I just bought a 2020 Yfz450r se this week, what first upgrades do you recommend

[@TeamWaxOffroad]

As far as the tuning, the video explains it well enough. Just have the ECU reprogrammed. Aftermarket exhausts are optional and don’t do much for your power gain.

[@ronnielutz3197]

I just took both my 2020s to dealer and they put a factory program in them after they was broke in and took the spark arrestor out of the exhaust and they both run great . And that was free. Under warranty cause of the running lean. Problem

Quick question I am planing on sending my ECU to Pep in Cali to get it flashed to accommodate for my mods, since I seen you had a flash done by them do you think it’s worth it and does it fix that bog and lean these bikes have was it a waste of money? or is going with a piggy back Tune way better?

it definitely does the job and worth every penny

Hey man. How do I get in contact wit PEP I’ve tried every way possible to contact them and no response. Or do I just need to ship the Ecu to them without contacting them? Hopefully you can help me out

[@TeamWaxOffroad]

i wouldn’t ship it to them without contacting them first, they should respond through facebook or instagram, that’s what we’ve always contacted them through

[@dustinrichards8401]

Fci intake, full system fmf 4.1 with power Bomb header or mega bomb, and a vortex ecu really wakes it up

[@Marselino1996]

Did you use the reflash ecu before installing the parts you were going to put on the Yfz450r? I’m about to go drop off my ecu and ship it off, I’m going to install the Rossier exhaust and fuel customs intake. I hope to see a big difference

[@TeamWaxOffroad]

No we did the reflash after putting the parts on. Tell PEP the mods you are going to put on your Yfz instead of the ones already on (stock pipe). That way they can tune it to those settings.

[@Davido50]

Arent newer YFZ450s quick enough? Get a Moflo air box cover.. you get 3hp & cleaner airflow. Change that engine oil every 10hrs MAX. Mobil 1 4T racing or Maxima full synthetic only. "RECYCLE OLD OIL".

[@kylebeach2316]

@@Davido50 yes they are quicker but you don't want to race a lean running quad unless you have spare money around for a rebuild

[@thethiefonthecross9092]

@@Davido50 that might be enough for you but some people want a little bit more especially when they love climbing gigantic Sandy Hills. I love climbing Hills and I tried my buddies 450 that had the fuel controller air lid box removed and pipes that thing Max out quick you don't have to worry about downshifting those tires stay spinning like mad crazy the only negative side I would say for the YFZ450 is it's a REV monster and if you weigh a lot it's almost like if your horse beating it a little bit if you're a heavy person 250 plus I would recommend the Raptor 700 you will notice a big difference and it won't feel like your horse beating it all the time

[@erikolivares6244]

As of July 3 2024 do you still recommend this reflash and how's your bike running if you haven't change it, also is the sale still active lol

[@danielreynoso8981]

I did the ECU reflash with PEP Performance and it worked well, I still had a bog on it, but it definitely ran much better than the stock ECU. But after a couple of years, I decided to get rid off the bog completely, so I purchased the Vortex and the bog is 100% gone. So, if you don't mind the bog, the the ECU reflash is good. But if you really want to get rid off the bog, then go Vortex. This way don't throw your money like I did. I spent $300 for the flash ECU, then spent $775 for the Vortex

[@connersnow298]

It’s same thing if they tune the stock and the vortex ? You have the same power gain ?

[@leroywitt-djs-7466]

I have a question. If I have PEP reprogram my ecu and I have a problem with my atv. Like the engine light comes on and I take it to my local deal. If they flash the ecu will I lose my reprogram from PEP ?

Does the carb models also run lean too? Or isit just the fuel injected models. I might be going to look at a 2013 carb model yfz and wondering if it has the same issue

[@TeamWaxOffroad]

This is for the fuel injected ones, because of the California emissions. The carb ones shouldn't run lean unless someone has messed with it

[@davidcoombs1874]

I got a power commander v with the 02 sensor for it. I paired that with the RS 2 exhaust and my air fuel ratio is 12 to 1. I’m new to modding, I have a 2020 YFZ 450R SE. I also have a k&n cold air intake and an open face air box with screen. Is there anything else I should do or could have done better and what mods would you recommend? It went 75mph stock and now goes 84.

[@TeamWaxOffroad]

I'm not a huge fan of the little programmers but if it works for you and cuts the dying ad spitting out of your quad then stick with it. If it still cuts out and dies I highly recommend the PEP reflash. As far as mods, I don't think there's anything else that needs to be done o yours haha! As long as she runs like a beast just leave her at that!

[@Davido50]

Thats plenty fast! Concentrate on keeping your quad running well & lasting a long time w/clean air filters & quality engine oils! Mobil 1 4T racing or Maxima full synthetic ..change every 10hrs & recycle ♻️ old stuff!

[@danielreynoso8981]

I would suggest getting rid off the AIS. The AIS can cause back fires. 38 Motosports has a AIS Delete kit for $25 and it's easy to do. It's a cheap mod

@Christian Poulsen when you send the ECU out, tell them the specific exhaust you're putting on it.

@@TeamWaxOffroad the only weird thing is I have never heard nobody complain about the optimizers before everybody's using them I drove a 450 with one and it was a monster like why would I complain or why would anybody complain about that?

this may work. but if I had a dollar for everyone who cheaped out and didn't get the vortex and had issues I would be rich. vortex just works and does it better then all other options. its funny people who buy a brand new one for like 9k then cheap out on upgrades. like my friend told me before I got mine be prepared to put 1500 to 2k into it. to make it at full potential

It was junk, tried with it for hours, called tech support, nothing worked, helped barley any. Definitely not enough to be worth the price.

If you don't have a basic knowledge of how to read and adjust fuel maps the pc5 isn't for you. It's not as simple as plug and play, but it offers a ton more adjustment IF you know what you're doing with it. The oc5 gets a lot of bad reviews because people think you can just plug it in and pick a preprogrammed random map off dynojet website and it's going to work flawlessly. I've got the pc5 on my 09 yfz450r mx quad with tons of engine work and the pc5 gives me all the adjustment I could ever need.
