The only one who can answer that is someone who’s ran both sizes on the same truck. I’ve read people praising how well their 369 tows with 175/80s without being laggy. I’ve talked to mikeeg02 with 238/100s and a 66/74/1.0, Lakebum with stock ADs and a 64/74/.91 and our setups seem to run the same as far as being cool and clean while lugging a heavy load. With 80% nozzles and 35” tires, yours should run identical to mine right up until you exceed 200cc of fuel.

1023diesel tunes, live tuned by Dusty. Not sure on the PW, but fairly low. I can ask Dusty what he is calling for, but I have a screwy Cali PCM that is not as easy to tune as all the others. Scanner shows ~3400 icp as long as i stay in the throttle. Full Force 250/100's built off of my old 350/200's.

Will make 47 PSI with out trying empty. It is not a haze in tune 4 it is a significant amount of smoke, and just more smoke in tune 5.

It drives amazing in all the tunes, just does not have the airflow on top. Changing to a 1.0 would not buy me anything, nor do I feel a 369/1.0 would help.

I will say these SXE turbos are leaps and bounds above what we had available 10 years ago when it took a 76MM turbo to make the power we do now, tuning also plays a big role.

Have you measured your back pressure at all? When I did mine, Carson really talked me into the 1.0 and I'm glad he did. I wish someone with a .9 would measure boost:back pressure. Mine stays 1:1 to 40ish psi, then goes up to about 44-45 with ~65 psi of back pressure. Which is on the edge of comfortable from the turbo people I've talked with. I just wonder how that one if you're would work with more room in the exhaust. May not be an appreciable amount though.

Thatís insane. If I tried to do that with my current setup the pistons would be dripping out the exhaust from the EGTS. I guess I could go with a 366 1.0 and if itís too laggy down low swap a .9 housing on that sum btch

Just got off the phone with someone at CSD. Recommended a 369. They run that on their shop truck with 160/stock injectors. Looking like I’ll prob go with a 366

FWIW, I've yet to read of any combination of an SXE turbo on a 7.3 NOT work well.

Still trying to decide on what to pull the trigger on

With 35s, and wanting to tow and be most DD friendly, I would just get the 364.5/74 with a 1.0 housing. The differences in performance between them are so minimal from the reports out there, but just to be safe with 35s and potential in town traffic, that is what I would do. I can just about promise you that no matter which you do, youre going to love it vs your current setup. Its quite literally a night and day difference.

If you remember, it will feel like the difference between before and after you added your T500 as far as in the seat feeling. Its that significant.
