Driving to tuner with breathing mods?
 

If I missed this I'm sorry, I did search first:

I have been running high flow cats and cat back untuned for about 2 years now and I know that is safe. My question is would it be un safe to drive an hour to a tuner after installing the Z1 manifold and intakes. I'm extremely anal about the car and know that with all 4 breathing mods a tune is required. I have heard different trains of thought on it but I believe the hour ride at highway speeds as long as I stayed out of the top end would be completely safe. Opinions?

Disconnect your battery, drive a bit slow (or don't redline it) to let the ECU relearn.
You'll be fine.

I have intakes, headers, TPs, CBE, intake manifold, 10-20k untuned miles. No CELs (only for TPs once)

The trick is to drive like you normally drive. The learn process is happening constantly. You will be fine.

Thats kinda what I figured for the trip to the tuner. Z1 specifically states that you must have a tune with the plenum so I would tend to take their word for it as one of the headlining nissan tuners that it's harmfully lean to drive around untuned for extended periods of time
