Dually Club #3
Just did the first drive of my 06 6.0l with a new Powermax GT3788VA. So this is the first review of the turbo performance. First note is that the turbo is considerable louder. I like it but my wife will not. I might have to put my cat back in to quiet it down. You can also hear that the amount of fresh air moving through the turbo is considerably more. I did notice that the turbo is not as quick to light off and the throttle response is not as crisp as stock. But I will say that this new turbo harder and longer through the entire powerband. I have never put my truck on a dyno but I would guess that this turbo gave me at east 75 HP more. While I have not done any calculations on fuel mileage yet, it appears that I am getting better mpg. I will know more after a few tanks. The EGTs also appear to be lower but will know more tomorrow when I pull my trailer. Hope this helps those that are looking for a new turbo to decide that this is a very good alternative to the stocker.
