Okay, need to put some new plugs in the 408. It will be seeing 15 psi. What plugs are you guys running in FI application, heat range/part number will be very helpful. :thumb:

Cool, thanks for all the info. Between here and LS1tech it seems that the BR7EF plug is the most popular so I went with it. Factory gap on them came out to be .026" so I left them alone and dropped them straight in. Good news, my miss is gone. Number 8 spark plug had a split the length of the ceramic. Sure made a difference having it hit on all eight cylinders. Thanks Allen for the tip to turn on the misfire detection to find the culprit. Did I say I still can't program with HPTuners software? :laugh:
