Just got the the gtp-38r on the truck, and let me tell you this thing is bad ***!!! It's not to terribly loud, however you can here it spool up through thw whole powerband, sounds almost like a big truck, pulls really hard and is really smooth as well. I would highly recommend this turbo to anyone!!!

 

Congrats. Get some sticks and tuning, then it will whistle.

 

Stock sticks for now, i have the DP 5 positioin tuner, MBRP 5in straight piped exhaust as well as the the S&B cai. Runs really nice, but i must admit it's no where close to my duramaxes i used to own, but hey at least Ford didnt take any bail out money, even got rid of my s-10 and got an explorer, LOL also have isspro gauges. Im gonna have this truck for a very long time it only has 55,000 miles.

 

Congrats, love mine......
