kevinj27 Posted May 29, 2014 Report Share Posted May 29, 2014 I searched around and wasn't able to find anything on this. For the custom tunes you can buy, is there a difference between the 3.5L and 3.7L tunes? The only difference between the engines I can find is the 3.5L engine is bored out to 3.7L but everything else is the same. If everything else was the same, it would make me think the tunes would be the exact same. The reason I am asking is that I am buying a used SCT 3015 tuner with 3 custom tunes loaded for the 3.5L. I have the 3.7L and was curious if I could use these or if I would need to buy them separate......thanks, Quote Link to comment Share on other sites More sharing options...
nickf1011 Posted May 29, 2014 Report Share Posted May 29, 2014 The 3.5 tunes would probably work safely on the 3.7, but you might be able to get a bit more out of it with a custom tune specifically for the 3.7. Quote Link to comment Share on other sites More sharing options...
