Ok...I need my experts here (Double R and others)... I am SERIOUSLY considering swapping my EFI Live for Race ME Ultra. I have been having some issues (tuner response and tunes) with EFI Live (throwing O2 sensor codes when noO2 sensors are still on truck). Truck runs fine, but the MIL / CEL is driving my OCD Crazy!!!! Tuner says it is my truck or I forgot to unplug something (can tell me what though), but that's another story. I have been impressed by the user reviews on the Ultra. My questions are as follows: 1. Do I need to return truck to stock or can I just install Ultra over current EFI Live tunes? 2. I had a Smarty Jr on truck before deletes and it caused a dead pedal issue, has this been an issue with anyone using the Ultra? 3. What is the current thinking on when custom tuning for the Ultra may be available (I like the 12V sound and other things Ray has been showing)? 4. Anyone in the market for a CTS II and EFI Live Autocal??? Thanks in advance for any advice... TRUCK SPECS: 2012 Ram 2500 Mega, EFILive (for now), 4" FloPro exhaust, BD Throttle sensitivity Booster, BD 68RFE trans pressure lock, BD Booster Builder.
