I recently purchased a 95 RMS and I need a base tune to check the shift points for the trans. The previous owner thought the PCM was bad and replaced it, but it has a Roady Wagon tune in it and I am pretty sure that the gears in the wagon with 2.93's I have 2.56's in this car so I just want to be sure. Also with the new Tunercat or the updated version when you change the tire size and differential it should change the affected transmission values, correct. I am just curious I tweaked the original file that I had from my 9C1 as far as trans shift points, but it has a 3.08 gear in it, so I am assuming that these would be off a bit or different anyway. Also I had to replace the original trans with a newer one that I had which is a 96, is there any specifications as far as line pressure, etc. that would be different in a 96 trans? Thanks for the help.
