Midwest Diesel's Stroker 15 pump

Dzchey21 · Jul 10, 2015

So its a 1100US tune, which is the same as a 11-14 Performance tune.

My "stock" tune is 1000 US No smoke 500 HP
"tow" is 1100 No smoke 525 HP
"street" is 1500" Slight haze at WOT Dynod 600 HP
"performance" is 1700 Little more HAZE dynod 629 HP

The tow setting is right at 525 Corrected HP at this elevation Bone stock trucks do 315 or so corrected on the same dyno just as a reference.

i need this in my life

I understand 1600 is about the limit of a 15 pump but I might need straightened out on that.

Quality info Dzchey21. Thanks for the testing and reporting. Looks like I will be replacing my 15 pump with a stroker when they get released.

My Midwest tune is holding 1536us in performance and Morgan thinks it might have a little more in it

Thanks for the info Dustin. Just a few more questions.

Are you sure your only running 1400rpm in 6th at 67mph? Because at that speed I'm around 1600rpm and my current tires measure out about 33.5" tall on my truck. My other question is, how well does the Street Max spool in regular driving compared to an H&S tuned 6.4? I can't drive a 6.7 with a Street Max but I can probably drive my buddies tuned 6.4 for a frame of reference. He keeps it on the mild setting so the hottest tune I could drive would be the 250hp tune. Thanks.

67mph is 1400 rpm in 6th for me too.

Yeah but your on 35s with 3.31 gears. Dustin is using 33s with 3.55 gears. So you shouldn't be running the same rpm at the same speed.

True. I never studied his set-up.

jcain · Jul 13, 2015

Just for verification. 35s and 3.31s

Dzchey21 · Jul 14, 2015

I'll verify Ron again

Driving a tuned 6.4 is completely different imho the 6.4 hits harder off the bottom but seems to fall off up top a little. At least here at 6000 feet. To me tho the 6.4 isn't as fun to drive because the throttle is more touchy and they produce way more smoke to do the same task. When I had my candy cane truck running i tried to get it to run as smoke free as my 6.7 but it just killed the response from it. I basically had to make it smoke a little from a stop to make it fun to drive. Apples to apples tho spool up is close once you control the smoke. At 1200 rpm the 6.4 would lug through where the 6.7 will need to downshift. The main difference there is tho the 6.7 is so much smoother on gear selection and converter lock that you almost don't even notice when it happens.

It's really tough to compare but hopefully this helps you. I'm sure sea level evens out the playing field a bit.

Morgan, any word or thoughts for release to genpop? I'm ready for more fuel.

Not yet. Probably towards the end of the year.

Did I miss it or is that dpf on?
I remember at one time you were trying to see what the limit was with the dpf. If so it's amazing, either way is awesome numbers.

off buddy.

Its DPF off, i tried like hell but there just isnt enough control over the DPF tables with whats available for tuning. I think that its Do able but the right tables need adjustment so the DPF doesnt think its soot loaded or pressure loaded all the time.

Morgan i have about 3500 miles on it now. last 2000 have been towing
