I drove it 100 + miles twice like this before it was green stickered. Never did see much of a difference (amazing as that may sound)
Typically the secondary jet kicks in at a specific rpm range to help from starving fuel (maybe Glen can help out on the specifics of this one?)
But cruising my truck all the way up and down Ice House Rd to the Rubicon I had that engine screaming at 3500-4000 rpm's in 3rd gear and it felt no different then if that jet wasn't plugged off.
