So, I've always seen mixed reviews on intercoolers, so I figured it was time that we got some solid data on one. Peter from Alradco was all about helping make it happen, so we came up with a game plan to get some good solid info on this intercooler doing what most of us do with our trucks 
Started off with a raw intercooler from Alradco (no coating or polish) and Nathannial and I went to the track the first evening I could! Obviously we were at Bandimere, and Density Altitude was 8700' or so that night. I made 3 passes, and datalogged each pass. Each pass, I pegged the EGT sensor, so it's tough to say how toasty things got lol. I tried to stay consistent and my best pass was 12.3 at 111.67. Anyway, here are the slips and the Intercooler after we swapped it!
To recap - Peaks were:
EGT: 1760+ :lookaround:
Boost: 69 Psi
12.3 @ 111.67
And here's a video of one of my stock intercooler passes. Pay attention to smoke output.

Swapping the Intercooler was smooth... really no hiccups aside from 1.) I forgot a 10mm socket somehow, and 2.) The brackets for my lightbar were in the way a little bit. Everything lined up perfect.
On to the good stuff! Now with the intercooler I made 2 more passes and datalogged each. I was shocked at the results.
The truck picked up almost 2 tenths and almost 2 mph! Running the MPH through the calculator shows the truck picked up 33 horsepower
Looking at the datalogs for these 2 runs, peak EGT's were 1691* and 1680* and boost was 71 psi. Looks like a drop of 160+* EGT's and 2 psi more boost with the intercooler!
Additionally, smoke output was lower... you can see in the video how much quicker it clears up.

On the drive home, EGT's hung right around 50* cooler than I would normally see through the same stretches. I confirmed that over the next several days of driving, EGT's seemed to stay 50* lower than with the stocker.
On top of that, my truck looks much better with an Intercooler behind the grill!
