Default Secondaries

Someone on Corvette Forum asked the question
Who still uses their secondaries? I thought this
would be a great poll question.
So, who still has functional secondaries on their Z?

Definitely working secondaries for me. One of the coolest features a ZR-1 has. I even asked Marc to leave "high power mode OFF" as standard when he programmed my chip.

Thumbs up for working secondaries and the need to activate them!

Still use the secondary's on my 185,000 mile 90. The jolt when they open lets you know your driving a ZR-1.

I like the secondaries as built primarily due to emissions standard in Japan and it is one of the cool features of the LT5 design. The day there are no longer parts to keep it working I will eliminate them and go from there, but I have spares of everything so it should be working in my lifetime of ownership.

Concur......Functional Secondaries are one of the "Cool Features" of the LT5 design

I have one ZR-1 with secondaries eliminated and other ZR-1s with completely functional Secondaries

Well, just to B different here, mine are eliminated due in part b/c they were smaller than the ports after I ported the runners. (37.5mm+). But, even before the porting, I had Marc eliminate that "feature" after my 2nd dive under the plenum fixing chit (leaks). I've NEVER missed them for a second. And, I love the instantaneous throttle response! Good riddance! Besides...Parts that don't exist don't cost much and they seldom break!
