I am thinking that I might break down and let the new flash get done to my truck. This being the inductive heating flash for the injectors. One question is this will the pcm flash for the injectors include all previous running changes? The one I am really after is the trans logic change that pertains to the TSB 07-6-9 6.0L DIESEL ENGINE - BUCK/JERK WHEN PULLING LARGE/HEAVY GOOSE NECK TRAILER and want ot make sure if I step up and have the latest flash done it will actually do what I want it to do. Secondly, my dealer knows I have a Edge Platinum, I know they know, they have done warranty work in the past with it hooked up but never a flash. Do I need to unhook it just for the purpose of the flash or will the Edge even make a difference? I wouldn't think so but just want to be sure. Thanks all.

The inductive heating strategy is part of the FICM flash and can be done separately from the PCM/TCM/FICM package that owners usually get....

Now... this is presupposing that you can find a tech that understands how to do this.

You will be further ahead to disconnect the programmer for the reflash.... It's not a matter of the dealer knowing i is there or not but you ae dealing with computer programming.

There is every likelihood that leaving it connected *MAY* not have any ill effects on either the programmer of the PCM..... How lucky do you feel?

In my job, I cannot leave anything to chance... it can come back to bite me.

Return the PCM to stock, disconnect the tuner... be done with it. No guesswork... no chances....
