A grand for a dyno tune is a little expensive I would think.
More like $30 to run it and $300 for a custom map.
Well good luck and I'd sure take em off you hands,
but I understand wanting to keep them for sure.
You might try Dobeck performance,
I've had real good luck with my Dobeck for adjusting my fuel,
that way you could keep your pipes on for less than $200,
plus they give a veterans discount if that applies.
