Alright here are first impressions just on the 20 minute drive home from my parent's house...
The tubes provide all drivability improvements and zero performance gains as suspected. I'm running around on +150hp because I like to party so that's probably why I feel a difference.
Completely smoothed out the application of boost. No more spikes like it used to and it does build quicker too. Cruising it actually dropped pressure until it's needed so there's definitely room for a bump in economy because of that. Holds boost better and is much more consistent. We'll see if my findings still hold true throughout the week.
Driver's side was a walk in the park to install. Passenger side... it's tighter than a tick's ass trying to make everything fit but it does work.
