So, I picked up an AMS intercooler at a really good price from a personal sale. Anyway, as I am leaving one of the guys says that I should expect to lose about 2 lbs of boost due to the increase of surface area being larger. Does this sound correct? BTW I am on stock turbo

No. The pressure drop should be minimal, like .5 psi. The AMS FMIC has a good core.

Thanks Chet, enjoy your vacation!! This thing might not be on when you get back. All depends if my f'in arm heals. Still might need a hand if you can.

Also, It's almost 4 inches thick, but the frontal surface area shouldn't matter since the same amount will be exposed.

How is your car running?

IMO a 4inch core IC will definetly make a noticable difference without being tuned in.

2 psi is possible, i know on my cobalt i lost around that much from going bigger fmic, just like when you run in cold weather you boost less because engine doesnt have to work as hard

I still haven't put it on, so I can't gauge yet. I will post any noticeable difference . I just don't want a loss in power or additional lag.

If I understand this correctly, the only reason you might lose boost is because the intercooler is more efficient, resulting in cooler charge air temps, which in turn lowers the amount of boost needed to reach your target load. This translates into the same power with less boost. Once you get tuned to turn the boost back up, you'll make even more power.

A friend of mine installed a 4 inch IC without tune, took it out for a blast and came back in limp mode.

Even if it does drop the pressure more than 1 psi, it won't add any lag, and it should make the same power because of the new I/C cooling enhancement.

Unless he is tuned (if at all) on PSI based boost control and upward boost correction is enabled, then he should be hitting the same psi regardless of air temps etc.

He's not, he is tuned load based
