im going to have my tcm module flashed on thursday but i was concerned about the additional ecm flash that the dealer said that they would perform...is there anything negative about any of the post 2000 ecm updates that would lead me to decline the ecm flash???...i know that the ecm that now runs the 5.9 in my TJ is a BEAST ...BUT... the one that i had running it before had the "DEATH FLASH" performed on it by mopar and that update literally KILLS the performance of the engine...i dont want to subject my WJ to that same fate. thanks in advance guys
