Back in September, I had my tuner stolen and was stuck with my Bama 93R tune, which had no problems. But for Christmas, my parents were generous enough to buy a replacement tuner (although it was delivered on my birthday 3 days ago) and the first thing I did was call SCT to put my stock tune (had a weird feeling last year that I should backup my stock tune) in my new tuner so I can have my actual stock tune listed as the stock file on my new tuner.
So after I brought my car to stock tune, I uploaded my new Bama tunes on my tuner, plugged it in and when I put the 93 Hybrid tune in my car, my car idle DROPPED to around 100-200 RPMs and jumped right back up to 1200 RPMs. After a while, it started to idle like it should, but the car was shaking a little bit and eventually dropped to around 400 RPMs before it jumped back up to normal RPMs, still shaking a bit (I have this on the video I attached). I thought maybe something was up with the Hybrid tune so I uploaded the Race tune this time. I turned it back on and it died. I decided to record it again to show you guys and American Muscle/Bama what problems I'm specifically having. Until then, I have my stock tune in but I might put in my old 93R tune from before.
Thanks in advance guys, I really appreciate help or advice you guys can give me.
