Product Reviews

2014 Mustang GT
- Long Tube Headers, Cold Air Intake, X-Pipe w/high flow cats, GT500 mufflers. 93 octane. 3.73 gears.

Contacted Steeda on 07/01/16 at approximately 2 PM, placed an order for a tune with the listed mods. Received an email with the completed tune at 4 PM. Yes, only 2 hours later!!!!!!!!!!! I was so shocked that i called and asked if that was the actual tune. Anyways, the car runs great and the customer service at Steeda is by far the best. I have dealt with many mustang mod companies over the past two years, but Steeda is by far the best.

My 2015 GT is the 4th vehicle I have enrolled in Tunes for Life with Steeda. They continue to impress so I continue to come back.

I have this paired with the Steeda CAI on my GT and the difference is unreal! I did not expect the 93 octane tune would do so much, as the car's driving manners at part throttle and cruising are so smooth and factory like. At WOT, though, hold-on-for-your-life. The difference in power throughout the curve, throttle response and the speed with which the car climbs through the tach will have you giggling like a school child each time.

My tune was delivered in 1 business day - talk about prompt service. Thanks again Steeda!

Very impressed! I had an issue with the initial tune I received so had to have it resent so I called them up and had a new one within minutes. Hands down the best customer service I have dealt with. They truly care about their products and their customers. The tune is amazing, really what the car should drive like from the factory. Throttle response is so much better and the car pulls hard throughout the rpms, wish I could give it more than 5 stars

Went through another company for tunes for years. The last tune I got from them with the Steeda CAI was terrible so I simply removed the intake. I decided to try the Steeda tune and can say I will never go back. More power, smooth idle, and stock like drive ability until you step on it. I almost sold my intake due to it just sitting around in the garage. I'll never take it off again.

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!!

First let me start off by saying that I received the steeda tunes i ordered shockingly fast in under 3 hours of ordering them. Now i need to tell you the truth. You need to order these tunes immediately for your modular mustang. I have a 2011 5.0 coyote and was running Bama tunes for the past few months and i didnt know what i was missing. I asked steeda for a conservative 91 octane and a more aggressive 93 for the strip and so far the conservative 91 is running less timing and better AFR than the Bama and feels so much smoother and more powerful. It idles perfectly, better than stock with no little heart murmur that everyone with a cai experiences at idle. Im so impressed, and would but these tunes again in a heartbeat. Im never going back.

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.

I installed the tune and put a few driving cycles on it yesterday and am quite pleased. The car seems more eager to rev. It shifts a bit smoother since I am now shifting at a slightly higher RPM as a result. This is a happy by-product I did not see coming.

It does indeed feel more powerful in the low to mid-rpm ranges. It is a nice upgrade. I am most impressed with the tunes ability to retain stock driveability. There is no surging, no lurches from hanging RPMs, and power delivery feels more linear. I was worried about this due to past tuning experiences, but my worries were unfounded.I am not really interested in peak numbers, just how fun the car is to drive, so there probably won't be any dyno testing.

I purchased the SCT X4 tuner along with the Steeda CAI through another site about 6 months ago. Did a few other things along the way too (BBK 85mm TB, Axle-back exhaust, GMS Pro-Series COP's). I was using the SCT pre-loaded tunes that came with the tuner. There was a noticeable difference in performance compared to stock but something was definately off, especially the throttle response. Decided to go with Steeda cause they're here in FL were I'm from and live along with their reputation. All I can say is WOW what a difference!!! The car feels so much quicker, throttle response is crisp, and there's no hesitation during WOT. It's just a smooth hard pull all the way to the redline. I couldn't be happier with the decision to use Steeda for my custom tune. Next... headers!

I have the tunes for life with another well known company and they were having trouble tuning my 14 GT with basic bolt-ons. I had problems with acceleration and my car had no power and was not fun to drive.
After a frustrating 2 month back and forth period with them, I decided to search for a different company to write tunes for my car. I decided to go with Steeda because I have not seen one bad review about their tunes and because of their close relationship with Ford. I called and talked to a tech and he was really friendly and knowledgeable so I went with the tunes for life with Steeda.
I filled out the online tune build form and within no time, they had delivered my first tune. I loaded it up on my car and went out on my first test drive and I was pleasantly surprised. With their first tune, they had fixed all of my issues! My car had all of its power back and then some! It was a blast to drive and I was smiling the whole time!
What set Steeda apart was that I was able to tell them what my car was doing and with their first tune sent to me, they fixed my issues. They are extremely professional and proficient in their trade. I will be a customer for life.
