Hard to start cold
I'm having this problem where the car doesn't like to start when its about 50F or below, what I have to do is hold my foot on the gas or else it dies in about 2 seconds, I looked at all the warmup tables in HP Tuners and everything looked stock, does something need to be adjusted because of the supercharger being added?

Have you ever checked your air fuel ratio? Being a custom tune you really need to get a wide band AFR gauge. Pull your plugs and look them over. Are they gray or black?

Well I think its only when it'* warming up that it tuns rough, unfortunately whenever its totally cold I don't have time to pull out the scanner and laptop to check the commanded AFR, once it warms up it is totally fine, same for it I restart it when it is warm

what is the possibility of the IAC failing and not throwing a code? sometimes I hear it kick in and then when it doesn't I have to hold my foot on the gas until it warms up to ~200F then turn off then on then off again and then start and I'm good to go
