probably on a fully modded car, not just adding it onto a car with just a cai and light mods
at the bottom of the dyno chart from Protege Garage it says- * Dyno proven gains of 20 horsepower on stock vehicle, no other mods.
* Dyno proven gains of 20 pound feet of Torque on stock vehicle, no other mods.

I've done all my own installs and it's easy ... rate it a 2.
how long would you say it took? did you have a helper?
It took me a lot longer than 15 minutes to do it, but I'm a real novice. I took off my intake filter, the BPV, then the stocker. After that you have to switch the cold pipe, I had to go look up the torques for those bolts, I think it was about 90 inch lbs. Then I made some gaskets for the new IC to sit on, the stocker had some but I couldn't reuse them.
When I tried to get the rear hose reinstalled, I couldn't get it by myself so I had to go recruit my neighbor. He's a certified Toyota mechanic, so it was smooth sailing after that. I held the IC up a bit and he got the rear hose on a tightened the clamps.
I thanked him, gave him a 12 pack, and proceeded to put it all back together.
Then I reconnected the battery, started her up , let it idle 15 minutes. Took her out for a test drive, and enjoyed watching my BAT drop.
Why did you take off your intake filter and BPV? What do you mean by switch the cold pipe? Why couldn't you reuse your stock gaskets?
Replacing the intercooler itself doesn't actually gain you any horsepower. What it does do is modify the boost curve by reducing the pressure drop associated with the stock intercooler.
If you look at a boost graph from a stock intercooler vs an ETS, SU, or pretty much any FMIC/TMIC on the market, you'll see "roughly" a 2 psi difference.
Guess what happens if you add 2 psi to your car? + 20 hp, + 20 ft/lbs.
The intercooler is basically giving you two free psi, due to it's lesser pressure drop vs stock. That's what gives you the power increase.
