2013 300s 5.7 HEMI ISSUES

Hello.

After installing 91 octane tune I elected to turn off MDS and increase shift firmness. ECO light still comes on and shift firmness seems the same. I installed again and still no result.

Any ideas?

Thanks.

The Eco light has nothing to do with MDS being on or off.

I felt the same way about my charger but discovered the harder I accelerated, the harder it shifted. At wot I definitely felt a difference. Find a good on ramp somewhere see what happens.
