So I am curious if there is anyone on the forum that has ran both of these turbo set ups? I like the streetmax r since it is still vgt it seems that you can make great power and still tow heavy which I worry about since I have a 14k 5th wheel I lug around in the summer/fall months. I am also interested in the h&s non vgt kit as well, probably the 63mm since its not vgt I don't want my spool to suffer too much. Which turbo would you guys consider better? Does the Streetmax r have high back pressures or anything like that? I don't plan on doing anything else to my truck, right now it is ******d leveled and on 35s running GH SOTF tuning. The only other thing I have thought about doing is swapping to 4.10 or 4.30 gears I don't feel like I can ever get at the rpm I want and the speed I want with the 3.55s I currently have. I know ill lose some mpg on the hwy but seems like I will stay the same or even gain in town which is where most of my driving occurs. Thanks for all of the opinions guys!
