Just got predator few ?'s

[gtapro151]

Hi i just got the predator finally and ive been satisfied so far just having a few issues. Whenever i try to change anything under transmission no mater what tune i select it says "failed to update shift firmness etc". Why is this? Also i are all these adjustments made in the diablo tunes already and do the diablo tunes disable mds? Because im down to 13 mpg now and i was at 17. I have a 2005 chrysler 300c if that helps. Other then that its a great product. Got rid of that annoying lag on the highway when you floor it it actually works now lol doing burnouts on 24s. I have the 91 tune just to not risk getting knock but we have 93 in the area is it worth the upgrade from 91?

if all the shift stuff fail, you likely have an early 05, and need to have the TCM itself updated by a dealership to get it going.

Like the whole unit needs to be changed or just a update with the star scan tool? I know its a early one because it dosent have tpms and i was told only the first ones were lucky enough to not have it before that law was passed.

just the tcm needs to be updated.
