Does anyone have a chart or anything...the last time i got my computer tune the guy changed the mph on it and now the speedo is about 10 mph off...Normally i could cruise at 2,000 rpms in 6th on the hwy and be running 88 mph. But now it more like 78 mph...does anyone have a graph for a stock geared M6 w/ 3:42's...thanks!

 

if you have way to tweak your pcm, tuner cats or lt1 edit i have a 100% stock file for a m6 i can send and you can get what you need from it. the changes are just a few as i recall speed pulses for driveshaft revolution is i believe what you are looking for and need to change. there are also some speedo scalar functions. You may want to post in the computer section for a better answer or help
