4.6 14cux ecu upgrades

[rfurzer]

How do the Mark Adams Tornado , the Randall Smith and the standard ecu EPROMs compare with respect to midrange (towing) torque and part-throttle cruise fuel economy.?

distinct improvement with mine,, but lots of smaller things finally added up too...
like all LRV8's the faster you go the more the engine likes it,,
cruise economy? seriously? LOL....
