Dvour Posted October 18, 2016 Share Posted October 18, 2016 I just got my car pro tuned and on cold starts I'm having issues 4/5 times. It's not major but after all I've been through, it makes me paranoid. It will go low on rpms and shudder, then shoot up to 2k rpms and go back down - shudder and repeat. I've had a tune that did this before where I got a great street tuner to fix it but now I got a pro tune and it's doing it all over again. Is it a/f ratios? Is it a simple fix by my tuner? I'm waiting on him to contact me back but it's been a hard time getting ahold of him at the moment which is why I'm asking on here. Give me some thoughts, thanks Link to comment Share on other sites More sharing options...
xt2005bonbon Posted October 19, 2016 Share Posted October 19, 2016 Are you able to log? What do you use to monitor the various ECU parameters? If not, it'll be hard to help.
