I started hearing what seems to be the turbo spool up right after upgrading my fmic, uicp and licp all at once, is it normal? I still have the stock air box.

If you didn't change your intake, the sound of the turbo would not change much. If it's a whistling noise, definitely check for boost leaks.

Thanks for the response. I was able to do a log with the AP and i'm hitting target boost and sometimes higher , but as soon as i hit 26-27 psi it immediately drops , i'm so confused . how do i attach the file here?

I believe the cobb tune is suppose to hit target boost, and then taper down as it gets to redline.

I have no problem hitting target boost, but i can hear turbo spool with windows up or down even thou i'm not supposed to?

I heard my turbo spool when my car was stock. I'm not sure if it was real loud with the windows up though

if your logs aren't abnormal, you should be fine.
I would check all connections and retighten them

Well is it normal to spike up to 26 psi and immediately drop to 23-22 psi?

The tune on the AP should tell you the target boost level. If the max boost is 26, then you should see a peak at 26 and then it taper down.

Log a 3rd gear pull or two and send it to Marshall for him to check it out.
