Feel the boast.
Definitely noticed the boast with no turbo lag or drop off of acceleration. Worked well with 2018 Eco-boast 1 speed transmission:Helpful (1)

After day one, on my first pull at the highest setting, check engine light came on. Code for underboost. I guess i kind of expected that, so I turned the knob down to 75 after one week in the vehicle, and maybe 9 or 10 WOT incidents, engine develops a knock. Really loud, double rapping noise from the lower end. At the dealer now, and they're saying it needs an engine. I have no doubt in my mind this product is the cause as before product was installed, never had an issue with the ecoboost. Absolutely terrible to think I lost a $5000 engine to a $309 knob. No confidence. I'm mortified at what my bill will be if this voids my warranty.Helpful (0)

EXCELLENT GAINS BUT BEWARE
The boostmax made a very noticeable difference in my 2017 ecoboosts performance! Its pulls way harder than stock. You MUST listen to your engine though when you turn the controller knob up past `!! I heard some detonation every now and then but corrected it somewhat by using one step colder plugs and running some octane boost on top of the 94 octane fuel i get from petro canada. I still turn my music down when doing WOT pulls so i can hear my engine clearly. Other than that, the boostmax is a great mod for anyone looking to gain some serious power while not voiding your warranty if of course, you remove it from your car before bringing it in for any work at the dealership.Helpful (0)

Doesn't flash your ECU.
Significant noticeable power gains with out making any undo able changes! I'm using the red 87 octane chip running 90 octane ethanol free gas and my gas mileage went up when I'm not in the turbo using the cruise control. I'm planning to get a Ranger later this year and this will be my first mod. Excellent Product!Helpful (7)

I spent 2 hrs fpr installation because I got some troubles with the Engine light and Wrench Light show up after first trying. But after all, those light went off. After the installation,I gave my car a ride test and i can feel a lot difference,more smoother and felt faster. P/s: for installation,when you guys plug all the cable into place and try to start the car,if the engine light and wrench light show up,try to unplug all the cable and plug it back after 30s. If it still show up,repeat that step. It will go off.Helpful (7)

It does work I hit 22/24 psi maybe fuel is better but I floor it all the time and drive hard with other little work the ecoboost can beat the 5.0 to 70mph after then the 5.0 takes over some times I go into overboost and have no turbo boost at all and I have to pull over turn the car off then back on Maybe 4 times now over in 1 yearHelpful (6)

Has improved my acceleration and the throttle response!Helpful (6)
"This performance booster also cuts down on the turbo lag often experienced in EcoBoost" A) Does anyone have any figures they could provide, I am installing mine in a couple weeks and want to be able to compare. B) How does this effect 0-60 and 1/4 mile times?
The JMS BoostMAX Performance Booster is adjustable to provide up to an additional 5PSI of boost which can add up to 44 additional HP. 0-06 and 1/4 mile times will improve, however due to a number of variables such as tire size and type, suspension, road surface, temperature and humidity, as well as elevation, hard numbers can not be attributed to this.
Would it be okay to run the JMS BoostMAX Performance Booster with an Unleashed tune at the same time?
Yes, it is okay to run a tune with the BoostMax.
So this chip WILL work in my 2018 ecoboost?
The JMS BoostMAX Performance Booster (Race Version) is compatible with 2018 EcoBoost models, in addition to 2015-2017 EcoBoost models.
What is the big difference compared to the standard JMS BoostMAX?
JMS BoostMAX - Race Version is more aggressive and has a better throttle response than the boost max. Also includes a option for 87 octane fuel.
If this is such a great product why have so many experienced eco boom using this
This will simply just boost the power some while using 87 octane gas.
The JMS BoostMAX Performance Booster and JMS PedalMax are not stackable as only only one connection is available for the throttle input.
The JMS BoostMAX Performance Booster and ThrottleMax Controller are not able to be used together as your Mustang only utilizes one throttle input. Only one of these devices can be used at a time.
The adjustments can be made on the fly.
This will work with the driving modes yes.
The JMS BoostMAX Performance Booster can be used with a Ford Performance Pro Cal Tune loaded to the vehicle. Since the JMS BoostMAX runs directly to your accelerator, they work independently from one another.
The Magnusson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, was created to protect consumer warranties. According to this act, a manufacturer such as Ford cannot void the warranty of a vehicle due to the use of an aftermarket part unless they can prove the aftermarket part directly cause or contributed to the failure of the vehicle.
This JMS BoostMAX Performance Booster will work on your Ecoboost without any other mods needing to be done.
You would have to check with the tuning company you are trying to use.
