I have the same issue man. I'm KA-T though. Idles fine on first start up/after sitting. Once its warmed up/start driving most often boosting and i come to a stop it will slowly lean out til max, then starts with the shitty idle. Or it will try and stumble, sometimes die if i dont blip the throttle.
Other times it will sit and idle like a fucking champ.
After i boost leak tested/fixed my car, response was better but the lean issue was more pronounced. Hesitation on tip-in throttle, runs fine if i'm dogging it (although rich) which implies boost/vac leaks.
I'm about to go back outside and replace more lines and see if anything can rid me of this forsaken problem.
