[QUOTE="djr4x4, post: 1245697, member: 20611"] I dunno why but it seems with the spartan tunes it throws the lie-o-tector off really bad.. Maybe the light peddle control? I dunno... I noticed on the 300 tune the lie-o-tector would read anywhere from 22-28 mpg pending my drive etc but hand calc I was anywhere in the 15-17 range for avg ( this is multiple fillups ).. When I swapped to the 210 tune the lie-o-tector dropped dramatically down, to around 19 for an avg mpg, and I'm sure it would drop more if I'd stay on that particular tune long enough. haha.. My avg hand calc would still be in the 15-16 range on avg.. [/QUOTE]
