I have a 2017 pp ecoboost 6spd and for some reason, even with the car warmed up, the 1st to 2nd gear shift is really notchy and requires more effort than the rest of the gears. It also makes an audible sound similar to when you pull the handbrake. This issue has been bugging me for some time...
Hello, I have a 2017 mustang ecoboost and I'm planning on taking out the mufflers and running pipes to the tips. Will I need a tune after doing this? Or will the ecu adjust for the reduced back pressure? I really want to make this car last forever.
