Product Reviews

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.

Fast tune updates from Steeda - every time I add a mod I let them know and they send me a new tune!

My GT is a bone stock Auto. Fun to drive right from the start but two things really needed to be changed. Throttle response and the very conservative shift logic from Ford. I wasn't too interested in getting firmer felt shifts, but those just add to the package. I have the Custom Performance Tune for my car and it made a night and day difference! What impressed me the most is the throttle response. Almost telepathic. Really. I just think about going faster and the car launches. Even at cruising speeds. The gears hold longer during acceleration to use the meat of the power band and downshifts are quick and there when you want them to be. I recommend this tune to everyone who has an Auto equipped GT. I would go so far as to say this is a necessary upgrade and how the car should behave when it comes off the lot. Communication to the Steeda team is quick and highly responsive. If you feel the tune needs to be tweaked to your desires, they make it happen. Bottom line is that I love their product and would highly recommend them to all Mustang owners.
