Hi I’m Pappy and I’m new to the forum and a new Mustang owner. I bought a 2017 Ecoboost premium last year and have been enjoying it, however it doesn’t have the getup and go that my previous car, a 370Z had so I’m looking to dress it up a bit.
The first thing I’m looking at is the 9603-M4 performance kit to add some power and I’m wondering if anyone has added this kit to their pony and what they’re experience was. I would appreciate some feedback.
Thanks.
