My street tires are 33's, my new track only slicks are 28's.
Is there anything I should change in my TCM tune when I'm at the track with the 28" tires?
I don't know if changing the Speedo Parameters, {HO136} Tire RPM's would help or not.
I have 2 TCM's, one for the street and one for the track, so if I changed a parameter in the race TCM it would only be once.

I can't change anything in my ECM, it's locked down.
