If you narrowed your decision to these 2 then Whipple is your best option, more power and a way more advanced and reliable tune.Appreciate all the input so far! I guess my eye is on the Whipple and Roush the most as it seems those are the most reputable and OEM like. So is it safe to say I'm okay with any of these on a stock Mustang GT for the long term?
To those who questioned, I do have BMR SP080 springs installed as well as 285/35/20 square Michelin PSS already. Thanks!
