I currently run spx wheel with kc turbine, so nothing fancy.
my last towing trip consisted of a run from Espanola N.M to Denver and back, 5k equipment trailer empty coming back 02 f250 crew cab on it didn't weigh in but safe to say easily 12k+/- 238/80 bitter root injectors .
Trip up empty php titan 65 Performance tune never egt issue at all, loaded 25hp heavy tow only time I had to drive by egt gauge was going up 9k' pass.
in 25hp tune my pw was max about 2ms, and 99% of the time truck ran cool with plenty of power on tap.
Running 315 75 16 with stock gears loaded, easily handled interstate speeds in 6th.
unloaded commuting the truck in 65 tune is WAY quicker than any stock injector hot tune, speed will get scary before temp does.
In 65 hp tune smoke is nonexistent, in normal driving up to about 3/4 throttle, after that it will put out a haze.
My commute takes me from home 5800' to work 7200'
the smoke is easier to manage than the stock injector dp tuned truck I had years ago.
I just put Bitterroot 238/100’s in my truck with GH tunes. Still ‘testing’ but my goal was more power than 160/0’s with no negative consequences.
I am interested to learn if we can pull the fuel back and max out MPG. Currently my lowest HP tune feels quite a bit more powerful than hot tune with the AC codes. So far, it appears I have to manage throttle input below 1800rpm to control smoke (6spd truck). But, I haven’t driven much and haven’t attempted to get tunes adjusted yet. (I WANT to give it 100% throttle at 1200rpm without smoke.., )
many tuners do not use the map sensor. Find a tuner that does use the map to limit low or no boost fueling that would probably go a long way toward your lofty goal,1200RPM zf6 and 100% throttle no smoke is tall order.
I recently started working with SDK and I know Dan uses the map.

Who told you that? A "tuner" trying to look good or convince you he's special or different? I assure you that is FALSE.
I very likely am, my truck has been a PITA to "dial" tuning in and that was one of the reasons I was given.
at this point, my truck is a mix of e99 L99 auto and manual.
the standard PHP tunes run good, but trying "custom" tuning has proven to be a challenge for the tuners I have contacted " e99 PCM super limited" " it doesn't do that on any of the other trucks with that tune" "there's nothing that I can do about that".
Have heard these phrases even when sending a video of changing between PHP tunes acting normal and their tunes acting up.
So you want 100% throttle under 1800 rpm and no smoke? With tunes and injectors installed and capable of alot more fuel than a stock setup?
Sounds like a pipe dream to me. If, however you wisely used progressive ( but quick) throttle input to increase desired GO POWER , you may find out from the tunes you already have their ( smokey factor) and when they start to smoke in response to throttle position.
To achieve the same results your looking for, you can ( practice ) your throttle input verses your desired response over and over on each tune until you reach max. satisfaction and least amount of smoke. Of course, on any MT the desired response will be more difficult, but can be done just as well.
On the BEST TUNE that gives you a decent response and less smoke, start recording data on those test runs and look at the numbers. Share that data with the tuner and tell him your desired outcome.
Then, I would find the BEST tune you already have that you have been working on regarding above suggestions and go back to the tuner and see if he can change anything in the tune to help. This is the cheapest, and FUN way to play around with what you already have.
I'm in the process of doing that now on my AT and I find there is a certain throttle position that I have to ( pass over) to reduce smoke when I first see it start out the tailpipe. So far, I find that it starts to smoke real bad when I'm demanding (more throttle) when it feels to me like I'm (LUGGING) the engine.
Put another way, it feels like I'm in ( too low rpm's) when I want the truck to GO FAST and my foot is too heavy at the same time.
For what it's worth, I have driven a lot of diesels in my lifetime and find all respond differently regardless of transmission attached. What I do find is we have the ability to wind out the gear/throttle combo for each ratio to get max desired power when you give the engine what it wants.

I agree and I’ve put bigger injectors in a bunch of these trucks. My plan is to do my own tuning soon, but hoping GH can dial it in a little better than what I think I have now (need to drive it more...) To be realistic, I don’t expect no smoke at 100% throttle - but I want to drive normally and not smoke. Specifically, I want to shift gears and accelerate from 1400-1600rpm without smoke unless I’m deep into the throttle.
