Hey guys. New to the forum but have been going back and forth with Les from Silver Bullet Tuning about tuning my dad's '06 Megacab. Well, initially, it was tuned with a Smarty Jr. Due to that, the ECM was "locked" and wouldn't allow a reading. As suggested by Les, we tried a full flash with a stock tune that he sent me. That was unsuccessful. We then tried another tune from Tune File Depot. Same results. We tried flashing both tunes more than once.
We are now stuck with a disabled vehicle and need it in 2 days! The V2's bootblock and firmware are up-to-date according to the control panel as well as the latest V7.5 and V8 software.
HELP!
