Stage 1 worth it? You feel any difference? I was looking at stage III but damn almost 3k....
You feel a noticeable difference. The largest reason is because out of the factory, Ford limits boost and torque in gears one and two to help prevent wheelspin. The Cobb tune removes that, allowing you to hit full boost in first and second. If it is dry and warm you can put the power down, but if its wet, it is spin city.
Luckily for you, if you are looking to go stage 3, there are a lot of brand choices for parts now so you're not forced to go with high priced brands such as Cobb and Mountune.
