HOW TO SHUT OFF MDS AND OR GET CUSTOM TUNE

[joespike5]

PART#U7137,LATEST 9R08-VERSION, 2009 DODGE RAM 5.7.

WILL SHUTTING OFF THE MDS GET RID OF THE LIFTER RATTLE WHEN THE ENGINE IS BETWEEM 4&8 CYLINDERS? HOW TO DO THIS? ALSO, CAN YOU RUN 89 OCTANE ON THE 87 PERFORMANCE TUNE? WHATS THE DIFFERENCE BETWEEN THE 87&93 PERFORMANCE TUNES BOTH PERFORMANCE AND FUEL MILEAGE WISE?

THANKS
JOE

LIFTER RATTLE???

i averaged 15.6 mpg with the 93 tune when i drive carefully, and 17 mpg with the 87 tune. way more power with the 93 tune though! i havent updated to the 9r08, mine the 9ro7 or some such. all i did was adjusty the throttle sensitivity +10%

i havent noticed any lifter rattle though.
