So I have a 2014 5.0 3.73 gears, JLT CAI, Flowmaster super 44'axel back and that's it. Im running the JLT 91 octane tune. When I go to adjustable parameters the gears are set at 3.31 I believe. If I change to 3.73 will everything else stay the same. Also is there anything else I should adjust I only ask because I don't notice much if any difference in performance. Thanks

Please post your last tune written out of the tunes folder.

ok

any thoughts? I saw a few forums you helped some guys out in before. Hope to get the same results. I can really tell the difference since I changed to 3.73 gears on the tune I posted. Gas milage sucks though on the highway im only getting 16-17. However, I didnt buy a 5.0 for the gas milage just think its bad based on the post of others.

Here you go sir. Sorry for the delay.

I am running the last tune that you sent me and when I come to a stop when my engine is cold my car will die. Also if I let it sit and idle for to long the idle will start to go up and down by 2-3 hundred rpm. I have also added an x-pipe by Pypes but it was doing it before the addition.

Try that

Attached is the data log after running the tune you just sent. Please review.

I am adding shorty Flowmaster scavenger series headers today can you adjust the last tune if needed?

shorty headers will not require any changes ideally.

Something is going on. Since I added them when cold started I get the loud pop noise from my JLT CAI like before adding the tune for the CAI. Then after warm and sitting at idle for more than a min or so idle starts to fluctuate to the point of almost dieing.

burn up an O2 harness?

No

Post what's in the tunes folder on the tool currently.
