i have a SCT X2... i do a lot of drag racing and have always used the SCT products and have had great luck with the tuners but i have always had a custom tunes of some sort... just wondering how the canned tunes that are in the X2 will do with fuel economy... not concerned with power, just fuel economy... never been in this situation... it was always concerned about power and don't worry with fuel economy... lol... funny how things change when you get older

 

If you are talking about the Xcal2, I did not think it came with canned tunes, only the Xcal3. But, I know very little about them, so that may be wrong.

 

you are correct, i have an X3 and a X2... the X2 doesn't have any canned tunes on it, just asked SCT... i guess i have to order a custom tune then...
