Product Reviews

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.
