I have MM3 and the Emissions tune from Ray.

I have 60k on this Trans and looking and working good but I want to upgrade the valve body for longevity and future higher line pressure tunes when I someday delete.

This is from an email I sent to Ray and thought I would run it by the community as well.

Thanks all!

Sorry for all the previous questions regarding the trans and valve bodies and tuning.

I have since found most of your posts on the subject on igotacummins.com.

So having said that. I decided to go with the ATS valve body.

I understand I can then do a city driving re learn process taking it easy for a while.

My question is....I have your emissions tune set on 30 horsepower mode now. Can I leave it there? or put it back to stock then back to 30 hp tune to reload trans tuning? I only have 60k on the truck and fluid always looks great so I'm not replacing the solenoid.

When I fully delete later I'll have you tune for higher line pressures unless you have suggestions there as well.

Thanks for all your help.
