BTW nice mod list!
Thanks! I actually already have a bunch of coding done, but had the cold start removed by my previous tune.

If anyone has cold start removed and is having issues with idle during cold start email with your VIN and we can supply you with a slighlty revised software version that can help. You can also check your software file if you have a copy of it and if it has "V13" in the description this is the lower idle version and can be revised by us if needed.

Small random idle fluctuations during cold start are normal but if you have normal cold start "which comes standard" on our kits and you are having abnormal issues with low idle during startup or driving contact your installation facility as this is not normal and can be a result of something hardware or installation related.
I don't have cold start removed then. I will email you a video next time, so you can tell me if what I am experiencing is normal. I will also follow up with my install facility as I need to get the blower fluid changed at 2500 miles. Thanks, Roman!
