No tune, just did the install today. Does this setup need a tune from the get-go or is it driveable without one? I'll be doing a tune once my high-flow cats come in (would be in if it wasn't for the COVID situation).

Did you install a tune during your intake install or did you drive around without a tune for a bit? How did the car run directly after install (if no tune right away)?

Edit: did some more messing around. Disassembled the whole intake and put it back together, made sure it was all good, still issues. Decided to remove the TB and use the ported intake/spacer with the factory TB and it idles fine; RPMs still stay a bit high but do come down, just slower than before; maybe the car just needs time to learn it? Maybe the car needs time to learn the 80mm TB too?

Edit #2: found a throttle body relearn procedure so followed that and the idle seemed much better, then took 'er for a spin and everything felt ok; RPM's still stay a bit high but do come back down; probably just needs a few more drives and all will be well.
