Default TB Opening Too Much

Will my ported tb opening too much at wot hurt performance? I know the voltage changes--I threw a po123 code, and know how to fix it, but I want to do it right and accurate, thus use HPTuner when I order it here in a little bit. I didn't know if it would hurt anything in the short term? Also, does this hurt performance alot at wot? Thanks.

Or bend the shaft. Haven't decided which. I installed the ls6 intake/ported tb at the same time, after 500 miles, decided to try her out. Would this have hurt the results?

Neither. Buy a set screw, drill and tap where you over carved it and put the set screw in. Adjust, repeat until you reach the right voltage.

The DTC sets at 4.65. No more than 4.6 should be fine.
