What a difference!
This item was simple to order and simple to install. The difference in driving my car is night and day. Throttle response is vastly improved over stock and everything just feels “correct” compared to the stock tuning which often felt rough or was hesitant to respond to input. Tune was installed on a 2011 Focus SES 5 speed with FSWERKS Cool-Flo intake and FSWERKS Stealth cat-back exhaust.
FSWERKS SCT X4 and tune
I Highly recommend this specially if you already have fswerks race exhaust and a cold air intake the car comes alive I have all of this on my 04 ZTS with the 2.3l and the car is so different now for the better 100% Recommend and 100% would buy again
Great help from Raffi and really woke up the engine. Thanks again fswerks
Great tuner great support
Tune our ford focus zx3 dirt oval race car was easy to install an any questions I had support was there every time would I recommend this tuner yes
Worked great,night and day difference
Woke up the old 2003 ford focus zx3. Very fun to drive now. Wish I had purchased this sooner.
Yo I was able to retard my timing and if you really want to you can preload tunes on it I do believe.
Absolutely amazing great customer service
Appreciate your feedback Seth :-)
SCTx4 for 08 focus MT
Raffi helped me and was super nice and knowledgeable. Tune works great. Really smoothed out the car for better drivability. Thank you FSWERKS
No problems with delivery and everything came on time.
I wrote a review before I even got this because their customer service is exactly what customer service should be. Excellent communication and response. Got the tuner and it took a couple of minutes. My son still had 3/4 tank of low octane fuel but we filed it the rest of the way with higher octane. Definitely a kick where it counts. I imagine it will only get better as more high octane fuel goes through it. The vehicle did chase idle a couple of times, I should have done the tune cold and let it idle to hot so the new systems could learn better. But I’m really happy with what it has done so far.
Absolute pleasure to work with
I want to start with the fact that I have not received the item yet. That being said, I ordered this and filled out the info wrong, the dude tuning it called me to verify and correct the info. I called them before ordering to check everything and the guy remembered me when he called me back. I just wish they offered more stuff for my vehicle so I could have this level of customer service every part I order.
Thank you Phillip :-)
Best Investment I made
Plug and play as it says. Totally changed my car performance wise and it runs smoother. Not instantly noticeable but after 2 days for me it was very noticeable
super easy use and install just make sure your online, really made a night and day change to my focus with the header and exhaust + the tune i feel like. I bought a new car
Excellent easy to use
Very straight forward. Easy to use and easy to understand. Works flawlessly. It got me motivated to get the Advantage III software to learn to custome tune my car .
Exactly what you need, buy it now
It was one of the best purchases I’ve made for the car, really woke it up.
Big improvement over stock.
Big difference. Went from a bone stock 2005 Focus ZX4 ST to many upgrades to increase the drivability of this car... and wow what a difference! Upgraded the clutch to the Excedy stage 1 clutch, did the fswerks race header, fswerks stealth exhaust, fswerks intake, and some aftermarket motor mounts. Also got the Flasher, with the fswerks 91oct tune, and with everything really woke the car up. Super easy to tune the car, Raffi had the tune to me before I even got home from picking up the flasher from them (I live near by, and they offer will-call which is awesome! 10/10 would recommend for every ZX4 ST owner!
That extra kick ;)
Easy Plug-and-Play OBD Tuner, just hooked it up after my 93 octane refuel and BAM!!! My Focus can hit 100 mph in 4th gear (no speed limiter anymore haha) and has an even more beautiful exhaust note with the ITG Cold Air Intake and FSWERKS Race Exhaust set up from before. Did I mention I hit 36 mpg on the highway, or at least until flooring it? Yeah, it's efficient when you need it to be as well. Since I can buy new tunes down the road, this is a lifetime investment that I'm glad I made. Next step, turbo, race headers, engine rebuild, weight reduction, rims... Ok that's too much probably but the SCT is ready for any crazy changes I make to this car. Thanks FSWERKS as always for your support since your customer service reps on Facebook were patient with my endless questions and were able to give solid answers quickly when needed. 6/5 stars, cuz 5 isn't enough!!!
Thank you Chris :-)
A vast improvement over stock.
If you are thinking you need, this... You most likely do. Grab one, I did and am not displeased. They called me and offered me a custom solution to fit my heavy modified build. The extra options allowed me to reuse .my stock ecu for s build pushing 20psi :) would for sure but again. Amazing device and quality.
