Already running your 93 winter tune. But I wonder. Do you do the following Incase the octane is actually lower than 93 automatically.. "Auto Octane" adjust-ability for all pump gas fuel grades

Does the unleashed tunes increase boost if so is it recommended to replace plugs and change the gap?

Ecobeast7

  • The Unleashed Tuning X4/SF4 Power Flash Tuner will increase boost. Typically spark plugs are not required to be changed or have the gap adjusted, however depending on modifications, it may be required. We recommend speaking with Unleashed if your car is highly modified to ensure there is no additional changes required.

Hello minidave :when you answered the question about the tune effecting the other driving modes in the ecoboost mustang you weren't really clear can you please break it down a bit more (does it mean that you can tune all the driving modes? Thanks

RamonR

  • The Unleashed Tuning X4/SF4 Power Flash Tuner will only effect driving characteristics in your normal drive mode. In modes other than normal, the engine settings of the tune remains, however the OEM drive mode settings for trans shift points and pressures, throttle sensitivity, etc will revert to the OEM settings.

Hi I have a brand new 2017 Mustang EcoBoost I'm planning on buying this after I do a couple mods. Will this void my warranty on my car?

TrevorW

  • You will want to check with your local Ford Dealership, some are very accepting of modifications while others are not, so best to ask them so you will have a definite answer from the people performing your warranty work!

    UNLEASHED MY BEAST!

    I have MRT Res. Delete, Roush Axle-back, Roush CAI, and Mishimoto Catch Can. Was asked $1400 for 50-80 HP gain on a custom Dyno tune (includes new spark plugs, In-gauge mounted in center vent, dyno tune, and labor) from local shop who has installed all my stuff to date. But I have spent a lot on body work and the other bolt-ons, but wanted a tune sooner than later; all the reviews lead me to this awesome more affordable option. I run 93 octane only, worth every penny for quick easy noticeable gains. Maybe I will do the customs tune later by the shop if I get bigger turbo instead of upgrading to the GT; either way I have the SCT for my future needs! Awesome buy, all the good reviews are accurate! Unleashed unleashed my beast!

    Simply Amazing

    The SCT tuner is a nice device, easy to use and not too large to fit in my car. The tune from Torrie certainly made a huge difference with the power on my ecoboost! It feels faster, shifts better and just feels incredibly smooth. I surely wish Ford would get these cars out of factory with these Tunes. His service was almost 24/7 and it was probably some of the fastest responses I have ever gotten over email!

    LOVE IT! Wonderful tune and tunes.

    The SCT tuner is a very nice tune and easy to use. However, the tunes from Unleashed are AMAZING! The quickest I could get my ecoboost to go, with a Roush Cold Air Intake, before was a 5.8 second 0-60, after the tune my fastest 0-60 is now a 4.8. We'll worth the purchase. :) Torrie from unleashed tuning also got my tune back to me very quickly, within 45 minutes.

    Unleashed Ecobeast

    The level of performance from the 93 octane tune combined with a CAI is unbelievable. Definitely worth their asking price and the SCT tuner is very easy to use.. Once I gave Unleashed my vehicle info, they emailed my two custom tunes in about 20 mins or less. You can instantly feel the difference, but once you flip it over to Sport or track mode, it really comes alive

    What a difference

    Put the winter tune on my son's car today and what a huge difference. Well worth the money. I emailed Torrie with all the info for the car and within hours or even less I had the winter and summer tune back. Customer service is the best I've ever dealt with and I won't go anywhere else for future tunes.

    Excellent!

    Very easy to install, Torri (unleashed tuning) has been excellently responded and emailed the tune files back much quicker than expected. My 2015 Mustang Ecoboost with performance package has significantly less throttle/ turbo lag. I can feel a significant increase on torque. I would recommend this product to anyone wishes to get better performance to their Mustang engine.

    SCTX4 with Torrie Unleashed wow!

    Having tune unleashed with cai airaid and axle ford racing borla mufflers really made a big difference. Be nice to have a report from tuner stating what improvements he/she made from stock like, at rpm ranges what stats will i be running either to lean or to rich a/f raito but I guess that ancient Chinese secret when we submitted ecu strategy form. I give 5 stars and highly recommend to EBM owners.

    Great Bang for The Buck!

    Item worked just as described and offered tremendous pulling power all the way to redline. Surprisingly, fuel economy also increased slightly (1-2 mpg) with 87 Tune. Overall a great value. Would have been five stars; however, the only issue was the initial downloading the driver to my computer for the device. After that, process was very straight forward. Great way to improve performance without breaking the bank!
