I have a 2004 6.0/4L80e swapped into a K5 Blazer, but am having DBW pedal issues. Basically, 50% mechanical pedal travel is read as 100% in the PCM so the pedal is super sensitive.
I've read several posts that a 2006 tune could possibly be the fix. Would it cost me another 2 credits in order to do a write entire for this file?
If so, I'd rather not spend another $100 on a "maybe".
It would likely cost you 4 credits to do that but we do not recommend doing so, so you do so at your own risk of credits and/or hurting your ecm.
It doesn't have to be perfect, it just needs to be done in two weeks...

Thanks,
So, what are my options for fixing this issue?
I see plenty of threads about it but they all die before the problem gets resolved.
Thanks again.
Because this isn't a one size fits all question, you are talking about a swap application into a vehicle that we never supported. You should be asking these questions in the gen 3 car/truck section to see if anyone can give you some guidance as to what they might've done.

To experiment with this option, you would need a 2006 TAC Module, APP, and the short wiring harness that joins them together.
Always best to program an OS change using GM software and a Tech 2 / MDI / etc.
