Update
Update,
I received and applied a tune update from Bill.
Actually I received the update 10 / 5 but didn't download and try it until this morning due to a brain fart on my end.
I feel a definite performance increase over stock and an overall positive performance gain over the previous custom tune.
I haven't had the chance to put many miles on it since the updated file was installed but I can understand why folks like their custom tunes.
I don't know at this point if future tweaks will be needed but you can remove me from the disappointed with custom tune category.
I wish I could change the title to something more appropriate like "Custom tune issues? "
