Just got a stage 2 z1 tune for my berk resonatedtest pipes they sent me , I drove for about 100 miles now on idle my car wants to bog down and stall out while idling in drive.. took to the mechanic scanned my car found no codes everything was good and up to par. Checked for vacuum leaks didn't find anything of a basic search, no lights on dash what could this be

 

I would suggest contacting your tuner to have them check the log to see whats going on.

 

yeah im currently waiting for them to revise look over things
