For a DD looking for about 600 at the wheels, never towing, but maximizing fuel efficiency would it better to do a modded '15 swap or a 64.5SXE? Yes, I know it has a lot to do with tuning and driving style. I'm just asking for a general response assuming proper tuning and average driving.

stick with a vgt for sure...

I appreciate your short and concise answer! Part two here..SPE with 360 thrust bearing VS streetmax? A 66mm seems kinda big for my goals but unsure if it'll spool quicker than a normal 66 since it's VGT

i avoid SPE. Midwests' Streetmax X is 66 as well, also with a 360* thrust bearing. Best thing is they have good tuning as well. Spool is not affected as the turbine side is stock.

Why avoid SPE? Seems like a good deal since it includes all piping intercooler and turbo with thrust bearings

I just dont like the way they do business...I guess you are too new here to remember the chitshow that went down a few years ago with them on here.

Also, I haven't met anyone yet that likes their tuning.

Yea my brother had SPE tunning on his 13 and he switched in less than 30 days to GH tunning.

So from what I gathered here is the 15-16’s have a different turbo and make a bunch more power?

Correct

I’ve seen 600rwhp out of a hot tuned 15-16’. If that’s true. That’s amazing.

Cr500 · Sep 20, 2018

Does anyone here have experience using a ‘15 up gt37 with gt4094 inards?
If so who did your software to help make it right?
Im considering building one for my truck, but i wonder if its too big for everyday use.
Thanks.

Mine did a consistent 580-589 when I was still vgt.

Stock turbo? What can the stock motor handle safely? 700rwhp?

11-16 trucks can live at 700. i know of at least three 2017 trucks at 740ish and still ticking fine...

Mines at 680-689hp
Buddy of mine, 2011 has done 720-730hp

The 720 HP Non vgt I assume? These engines don't like those numbers with a vgt...

Sounds like the motor is good at 700 does that go for the trans as well?

Is it true to stay away from the 11’s something about a valve issue? Anyone have an idea what these trucks weigh.... 4 door shortbed 4x4 Lariat.

sootie · Sep 22, 2018

Trans will live a long while at 650+. Mine makes 668 and has been thrashed daily for years now. I have a comp unit sitting on the floor so I've been trying to break it to no avail!

The valve issue on the 11s was isolated to trucks built before April 11 I believe. But yes it is a real thing as my truck had the problem and got a new/used heart as a result

I lost my trans at 28,000. but my buddy has had his 2011 with stock trans at that power for 120,000 miles. Shows you the difference in those extra clutch packs I guess.

Has anyone on here purchased the ‘15 retrofit kit with the modded 66mm streetmax x from Midwest?? If so what all is included in that kit?
