Swapping Tunes Daily?

Quick Question...... I know it is probably a newbie question, but I figured i'd ask for my own knowledge.

Is there any problem with swapping between tunes on a day to day basis?

I find myself lately changing between my heavy tow and street tune often. Sometimes I do it daily or every other day.

Runs good on both, but my street tune is deff not up to the task of towing and my tow tune is smokey if I am heavy footing it around town.

Just trying to see if there are any known issues with doing this on a regular basis.

Thanks in advance.....

Very good question but I believe if done on a daily basses I would make sure you have a backed up stock file on your pc.

I have done more than 4 in a day for testing a number of times. I usually don't see any issues, except for the occasional shifting issues, but only on very OLD tunes and usually only until all the gears have been run through once. However, I do know at some point there will be a glitch that will require a master reboot or a stock reload to bring it back. It really becomes more of a PITA to have to keep switching with the potential risk that it entails.

My best economy tune is not my Extreme tune, but a mid tune with advance timing and boost that is just high enough to clean up my injectors. I guess I could get a tune reworked to be only extreme with the APS at 75% or greater. The same could be said for towing and performance, recognizing the requirement to not be too tempted to light the burners.

For day to day the PCM will be trying write the tables. If you keep swapping the parameters around it will just keep writing the tables with no conclusion.

I for one find it takes upwards of two weeks for tuning to settle in the PCM. I tow a boat so I keep an eye on the EGTs with my street file. I have a heavy tow tune loaded as stock on my PCM when needed.

I think you need some new tuning of just learn to stick with one file for your daily needs.
