Copy and pasting as I originally posted this under dodge but after connecting the dots, this seems like the better forum section.

I have a 2014 Ram 5.7l that i am currently trying to dyno tune, not having the least bit of success.

Truck has shorty headers, cai, and a cam. NO CAM PHASER, NO VVT. VVT has been disabled in the tune along with neural network.

First of all, i am only able to perform tuneable runs at above 4000-4500rpm due to not having access to adjust the parameters to keep it from downshifting, unless i pay $200 for the 4 tcm credits just to be able to perform a full dyno run. I am accepting that that is just not going to happen.

Primary issue though is, the very first run, not having touched anything to do with wot, has so far made the most power. Ever since that first run, power has decreased from there due to timing being pulled. Getting fuel dialed in does make more power than the tune i started with, however, there is still a 20hp/50lbft gap between what is makes now and what it made on the very first run. I also have run it multiple days now, so anything to do with heat has been ruled out. I have even copied the WOT base timing table over to the WOT Thermal table with no luck. Example of what i am seeing for timing: Very first run at 5k rpms the truck was running 16.5deg, whereas every run after that has been at most 10.5deg and as little as 8deg. I have even loaded the original tune i started with back in and it is still down 60hp because somehow actual timing is less than before. Also absolutely no knock retard in these runs so rule that out too. Nothing in the logs show any explanation for this, i have everything to do with ignition logged.
I had gotten to the point where i have added 8+ degrees to the WOT Base, WOT Thermal, MBT Base, WOT VVT Lockpin, and even Part Throttle base and while i actually did eventually make a bit more hp, torque was still way down and actually did start throwing kr in that region. Also, even though i was adding 8+ degrees, thats not atall how much it actually increased timing, more like an additional 4-6deg. I have also tried disabling anything to do with torque management spark with no luck.

I am currently at a loss right now as the original WOT settings make the most power and the least power on the same exact tune, and everything i can do to increase power puts me somewhere in the middle. FYI that first dyno run made 318hp and 361lbft and now on the same tune is making at most 300hp and 318lbft, running 11.6-12afr(again at stock fuel settings). I can post dyno runs and logs/tune if needed.

Also, this is not my first time tuning a hemi, but is the newest one i have tuned. Few weeks ago i tuned a 2013 charger hemi with vvt without issue. I have never had any type of issue like this on a dodge platform.

I have also been having some issues tuning a 2011 corvette. Mostly strange idle issues that i have never ran into before, again i have tuned many gm gen 3 and 4 vehicles in the past, but last week it did start throwing p0606 code, along with some communication codes related to pcm and tcm, went to write it after that(had a 2014 mustang in the past get a no start and communication codes and writing the tune back in fixed it) and it said "controller unlocker: time out" and would not let me write to it again. At that point, replaced pcm and reflashed with factory software, bought another license, and continued to tune. I was writing tunes to it this morning just fine, just went back to it and not when i try to write, it says "unlicensed vehicle". Does not pull up the window that says something like "show license options", it just simply says in the vehicle writer window unlicensed vehicle.

What i am wondering now, being that these 2 vehicles are having strange things happen and the only thing they have in common is the use of the same MPVI2, if this device is responsible. Might need to open a support ticket but want to see what you guys have to say first.

Another thing, i think about it, on both of these vehicles, in the scanner, when hitting the disconnect button, 9 times out of 10 i get an error saying: "unhandled exception has occured in your application. if you click continue, the application will ignore this error and attempt to continue. if you click quit, the app will close immediately. object reference not set to an instance of an object". Scanner works fine aside from that.
