    what's the best car cover??

    I also have a Steeda cover. It fits my 2011 Mustang GT perfectly and even has a hole for the rear antenna plus it has the Steeda logo on the front of the cover. It's a nice snug fit but I don't use it everyday cause I'm lazy and it takes about ten minutes to put it on and to adjust the straps...

    Experiences or Opinions of SCT from Steeda?

    I've used Steeda since 1993 and never had a problem with them. I live 20 miles south of them so anytime I want to upgrade something on my Mustang I set up an appointment. They're products are excellent as is their service.

    2011 Starting problem sometimes

    It may very well be the performance tune that's causing a problem. I don't recall having this happen until I had a performance tune (with added Steeda CAI) done to my 2011 Mustang GT in mid March. It doesn't happen often, maybe three times in the past few months.

    SCT Flash Tune + Steeda CAI = 40+Hp But Milage Suffers. I own a 2011 Mustang GT Premium automatic with stock 3.15 rear gears. Unhappy with the flat spot from 20 to 30 mph I had a SCT Performance Flash Tune and Steeda CAI added to the car. The car now has excellent throttle response but milage...
