I installed the CV fabrication intercooler using my stock tubing and a S&B cold air kit.been on the truck for a few months and now I noticed my boost is super low and I have the ford performance tune so I should be up around 24 psi.

If you watch the video it will show and I know it’s in vacuum at idle producing no boost

Try a pull at 65 in a higher gear. Your truck may be torque limited in 1st and 2nd.

Not saying that's 100% but just to be sure.

Double check all your connections. I upgraded my intercooler, intake and charge pipes along with the FP tune and had low boost. Turned out to be a loose clamp. I don’t ever see boost in the 24-26 range unless I have it in sport with the pedal to the floor.

Ok I was thinking the same might be the O-Rings in the coupler from either the charge pipes going in or the outlet to the throttle body

If you happened to remove the o-rings in the connectors to the intercooler when you replaced it, they are directional. Which way I don’t recall. When I added my Process West pipes I was careful to transfer them the same way they came out of the stock ones.

Also you could use your ProCal module to reset your KAM settings for any learned values from before you swapped the intercooler depending on how long you have been running with it. Will run weird for a few days till it relearns. Made my truck run way better after my swap.

The KAM reset worked thanks man

Yes vacuum until there is boost--without getting too technical.

Whenever you change an IC, you should always do a re-learn because now you have changed your pressure drop, so it needs to re-calibrate based on the change. Theoretically, a lower drop IC should be better for the turbo's (not counting added power), because you need lest boost going into the IC to get the desired pressure on the output EVEN IF there was no change in air temps.

But since you get lower air temps AND lower pressure drop, it's a double +, so I would imagine peak boost would average lower with a higher performance IC than with the stock unit.

Really what they are targeting is air density, at higher temps, you need more boost to get the same air density. So cooling helps, but less restriction also helps barring you don't have a massive increase in volume that creates a lot of lag. How does that help the turbo's?

1. The wastegates will be more open, so your not running the compressor as hard (aka less back pressure, less thermal loss etc.) to achieve the targeted air density.

2. Should help turbo-life since it's being used in more optimal range vs. at the upper limit as efficiency drops.

3. Should reduce average back pressure on the exhaust side since you not driving the turbo as hard to compress air.

4. Obviously you have more consistent performance since the IC won't heat soak hardly at all if ever, even if it does, it's likely to see lower max charge air temps than the stocker.

Stocker's aren't terrible like people claim, but an IC can net you another 1-2 tenths on a quarter mile due to heat soaking on the back half. You won't see heat soaking in the lower gears, but driving 5th - 7th gears at WOT, your dwell times are much longer and the loads are higher, so that's when you start to see all the heating = less timing advance. But your transmission will be slightly less happy as it's seeing higher average torque!

Any pics of the intercooler install? What was involved?
