Has anyone stacked the X2 City milage tune w/ their Smarty and had good results? So far, 250+ miles it's looking really good. I won't post #s yet because it's not over til it's over, but it's looking promising for a solid gain. BTW I'm running the beta 4.2 #1 on Smarty.

 

have not tried city but with hwy &4.4 stack really good results on #5 tune

 

what are others getting on quad x2 city alone? I've been thinking about that to help MPG's...

 

i dont have a smarty but i have a x2 on citympg,im running my pred on a non timing tune,i have nice throttle responce and seems to be getting better mpgs,almost all my driving is city so any gain is a good thing,does the smarty on 1 have a no timing option?ive read stacking 2 timing things could be bad,i notice more rattle if i use a timing tune on the pred and run the x2.good combo for the price though.
