Low RPM, high boost

Anybody else have this problem? It's almost like I gotta drive it like a stick! I don't know if it's just not downshifting fast enough, but it'll pull full boost in overdrive at like 55 mph. Not a huge deal, but sometimes I wish it would shift itself correctly.

Shadd.. seems to me I heard that your trans wasn't the healthiest at WC. Sounds like a possible future rebuild.

Sounds like a BCS or BCA acting up to me. Check for a vacuum leak or disconnected BCA.
