Also a custom tune is not to bad, I use SCT SF3 and you can get a custom tune for 75.00 from MPT performance.

Ordered new upstream sensors last week. They have 18" long wires so no extensions were needed. Installed those on Tuesday evening. Also installed 90 degree spacers for the rear sensors. Haven't gotten any codes and I've put Alittle over 100 miles on it.
