Great tune. Great Customer Service.

I bought a tuner from my friend that was not originally from FSWERK'S website, while the previous owner flashed it to FSWERKS tune along with resetting to factory settings, FSWERKS almost made me pay the 150$ but they kept their word and let me purchase the tune for 50$ and overall I'm 100% satisfied with my purchase. Would highly recommend FSWERKS.

Must have for mods!

I recently purchased a full exhaust system from FSWERKS and knew I had to update my 91 octane tune. I got a 93 tune with a rear O2 sensor delete, I have better acceleration and throttle response. I highly recommend getting a tune if you have any mods. And the guys here are awesome, very professional and considerate. Btw I was running my first tune for over a year no issues.

70,000 miles of excellent running

Some tuners have had success getting more power...but they end up frying pistons in the process, which isn't good. I've had ZED0 and RLA6 based 93 octane tunes on my SVT since 2004 with complete reliability and excellent fuel economy (mid-high 30's on the highway) and very much improved power along with drive-ability. The stock ZED0 (2004) tune is horrible without appreciable bottom end power (hence the 'weak clutch' reputation these cars got...not the clutch...no bottom end power) but these tunes both pull like a tractor down below 1000 rpm for ease pulling out. Revs on both should be kept above 2000 for normal driving where it's making enough torque to pull the car around even in the mountains but it really starts to snarl at 2500 and gets stronger as it revs clear to 7000 or so. The ZED0 intake cam timing is a bit less advanced than the RLA6 which improves the idle smoothness and makes the bottom end a bit stronger, but the RLA6 keeps bringing me back because it's more rowdy and comes on harder when breaking through 2500 and up. Both tunes pull well to the stock 7200 redline with little reason to go much past that as the power begins to fade. The Zetec isn't make to run like a Honda...it's a midrange torque type motor and SVT did a bang-up job with it. Have dealt with WRX (even STI) Subaru's from a roll up to 125 or so and VW turbo's haven't been much of a problem. You should see their faces when looking under the hood after a run....no turbo, nitrous or supercharger....they really get bummed. With a high flow cat and opened up intake box along with massaged MAF this engine runs really well for what it is. BRZ's won't even play because they know what's going to happen. I can't believe there are any SVT Foci left in the world without a tune, but if you're reading this I highly recommend the FSWERKS (previously Focus Sport) tunes.

Thanks very much for your feedback Robert :-)


Must have

Great, super easy to install. There is a noticeable gain in top end hp. This was paired with intake + exhaust from fswerks, in addition to it being tuned for 94 octane
