question about changing gear ratio. If I let the dealership intall the 3:73 differential and they reflash my car,
when I reload the 93 tune, will I still have to change gear ratio with the predator?
( 2010 SRT Challenger auto )

If you have lowered fan temps, just let it warm up before driving. Thankfully no emissions tests or inspections here in SC.

with smaller tires ( lower gear ratio ) could possibly run 1-2 tenths better

If he has a 185 deg stat, the LS fan should be set higher than 181

have 2010 srt challenger. options on predator menu are raise shift points, dosen't give option for how much. question is how much should I raise rev limiter to accomodate this. also, what rpm should it shift at after increasing shift point.

already have it with the 9r28. great tool !

how about 2010 srt challenger?

2010 SRT Challenger auto. Loaded stock tune for trip to dealership for dead battery, remote start not working. Noticed shifts were mushy. Re-loaded 91CAI tune, shifts firmed up. Question is does the tune max out firmness,or can it still be adjusted.

just got my first cel this week for t-stat. guess its the cooler weather. using jet also. when I went to napa, they said they didn't have a 180 stat. wish I had the part # then to give them. anyway, got a reply from mikel about sending tune to erase the code. ( just have to figure out how to do this )

got my first cel from changing to 180 tstat. nice to have my predator to clear the code!

thanks for the help.

installed 91 cai. adjusted fan settings for 180 t stat
planning on trying 93 cai. will I have to re adjust the fan temp settings again after installilng the 93 tune?
