I have a 2009 Silverado 6 speed with 5.3L, E38 pcm. Does anyone have a better update than VCM: 12630501 TCM: 24249179
The ones in the tune repository seem numerically older.
I have a flash from a 2010 6 speed 5.3L with VVT, E38 pcm. The VCM: 12636005 TCM: 24254909
Can I write that flash onto my 2009 PCM and expect it to work properly even though the 2009 doesn't have VVT?
The 2009 still has Variable cam spark tables in the tune though, which confuses me.
I drove this 2010 for about a month, and it ran like a scalded dog compared to the 2009 I purchased recently.
