Tune closed headers - open at track-o2's? kind of hard to tune open headers on the street, if tune closed, any guess as to the amount of rickness (if any ) which will occure if run open at track
( my 3" collectors open about 22-23" away from the 02's so the cool air should not get to them )
Thanks any/all replys

as long as your LTRIMs are locking to 0 at WOT shouldn't matter I'd think... at WOT the PCM doesn't use the O2s to adjust A/F ... If you drop the exhaust at the track I wouldn't imagine the time it takes to drive to the staging lanes, stage, and get ready to run would have a severe enough impact on LTRIMs to cause much of a difference when going WOT
