Hey guys I’m new to the mustang forum and I have a question for you guys. I’ve just added a Bama 87 performance tune to my 2017 GT. I was test driving it and I noticed the shift feel like they are jerky. My car is an automatic . My question is is their natural feeling because I read that the tune tightens the gear shifts. I just want to make sure because I don’t want my transmission to be effected. Thanks in advance for your respones.
