Love what it did for the car
Just added the tune and steeda’s CAI to my 2013 V6 Mustang. The difference it made in performance is very noticeable. Thanks Matt Henschke for helping me make my car better.

Tune is a must for V6
I recently had a tune written for my 2013 V6 manual, originally went the CAI route but for some reason my engine does not perform well with CAI. I had Steeda re-write tune for my stock air box, K&N filter and Airaid intake tube. Absolutely fantastic what a difference in the power band and low end torque, really woke up the engine. Sounds great and engine runs like a top, I would recommend getting a tune before any other mods, its a great place to start and Steeda's support has been great. 2013 V6 MCA manual, MBRP Axle Backs, Dynomax/Walker over axle pipes, Ford Racing X pipe, JLT catch can, Whiteline adjustable panhard bar and support brace, SR A-arm brace, Steeda LCA's and Sway Bars, DSS One piece Aluminum Driveshaft, BFG 255/45 18 front and rear, Roush chin spoiler, Boss 302 strut tower brace, SR rear shock tower brace.

this SCT 93 octane race tune has really turned my 2016 S550 automatic GT around
Yes sir this SCT 93 octane race tune has really turned my 2016 S550 automatic GT around she will now run a 12.5 @116 mph. with the all season tires and with a terrible 0-30 at 2.2 seconds. 3.55 rear sets. Idles almost like a pro-mod engine with that crackling lope. She bone stock other than the tune and an Airaid CAI

Awesome tune by Steeda!!
Loaded up my new Steeda 93-octane tune today, with the Proflow CAI restrictor tube removed from the MAF housing. NO MORE REV-HANG! The car shifts just like stock, and the rpms drop right where they need to. The car feels great with the bigger MAF housing, and an awesome tune by Steeda!!

this is the way it should have come from the factory
Just installed my Steeda tune for stock 93 octane this morning. it sounded healthier when I first started it up, throttle response is much better and it revs to redline much quicker. this is the way it should have come from the factory. Steeda claims almost 19 more rwhp on a manual. I love it so far.

Highly recommend this tuner
I was a bit unsure as to how this tuner would really do. I am a believer now! After installing a 93 octane race tune, twin 62mm throttle body, and a "Steeda" CAI....all i can say now is my car is a beast now. I highly recommend this tuner. easy to use, with simple on screen prompts, and more hp and torge, make it more than worth it!

Love it!
Tuned by Steeda! This thing is an animal! Great tune. Idles very sedately, revs fall through the range freely (better than stock). Love it!

Kudos to Steeda
I continue to be impressed by Steeda. My requests for tune revisions are completed in 24 hours and more importantly, the tunes themselves are the gold standard. I picked Steeda for it's reputation and I now know that reputation is well deserved. I hope you take it for the complement it is when I tell you the throttle response and modulation is BMW-like. I have tried other tunes and without fail come back to Steeda because the throttle is perfect.

The car just begs to be driven hard
Awesome tune!! Way better than Lund Tune . The car just begs to be driven hard. Fuel Mileage also improved. Now time for the Headers and an Intake. :))

Another good experience yet again
First thing I noticed was the throttle response is crisper... takes less pedal to get the car up to speed. Seems to want to accel with the slightest amount of gas. Midrange torque is increased by the butt meter and not just's noticeable. Feels great and can't wait for the intake to get here and the tune for restrictor removed. I am assuming it will be another good experience yet again.

Have not been disappointed yet
Ordered this tuner from Steeda because of previous experience buying from Steeda and their reputation for solid tunes. Order fulfilled and shipped quickly. Have not been disappointed yet.

Thank you for a great product
I have had Steeda custom tunes in two Coyote Mustangs and most recently my Cobra. Working with them on custom tunes is always a pleasure. Turn around time and service are second to none and the results are astounding. Each car had great gains in throttle response, horsepower and torque. I always run the 93 octane tunes on my cars and driveability is unaffected. Cruising around or daily driving is just as easy as stock, but step on it and and you have a whole different animal on your hands. I have trusted Steeda with each car thus far and would not turn to anyone else. Thank you for a great product.

Best upgrade on the market
Not only does this tuner by SCT give you 20+hp right out of the box, it allows you to feel at ease when ordering future mods since this same tuner can be used in conjunction.

Best Bang For The Buck
For the price, you can't go wrong with this mod. It's so easy to use and you can load any fuel-type of tune. Makes your car even faster! :)

Instant HP
This is the best mod you can do for your Mustang - the new SCT X4 is sleek and is very easy to use. Gained 30hp just with this mod alone.
