I Have The Banks 6 Gun Now , Is There Another Box That Cheap That I Can Put On Top Of That ? I Ve Had To Install A Valve Body So It It'll Stay On The High Setting Of The Banks. Anyone Using The New Sct Programmer ( The New SuPER Chip One ). And Last But Not Lease , I Was Getting 18 Miles Per Gallon With 265 Tires , I Put On 35" Tires And It Dropped Down To 14 - 16. :-{}
