I don't have much miles on it as in the city but initial impressions are good. In sport + mode it just feels all around more stout. Between shifts under full throttle you definitely hear BOV now which was not case before. In race mode it is really noticeable acceleration improvement and especially with trans in sport mode. BOV noise even more noticeable at shifts, I like it. I felt fast and furious!

Questions for Dinan:

1) Is it safe to drive around race mode frequently?
2) When in stock mode, is it doing anything or is simply bypassed all together?
3) Does it know what mode trans is in and is anything changed as a result?

4) Questions about app?

- When you press that little blue down arrow the one that say must be in boost gauge mode it seems to shift the gauge from negative or vacuum to starting point of 0psi. It does also seem to affect the max boost registered? What am I missing or what is this doing/saying?

I could only glance but seemed to be hitting 16psi at Sport+and 18psi in race but again, quick glance at gauge but clear difference.

-Is it instant like the app shows when you switch between modes.

4) Still need to find a good place to ziptie it. Right now its tie wrapped to a factory loom holder up on strut tower. Also I think the stock connector at boost sensor needs to be ziptied to something, its a big connector to be flopping around, not sure what yet. Right now its just tie wrapped to the connector plugged into sensor.
Glad you are enjoying it thus far.

1. It is safe to drive around in race mode all the time if you like. Would recommend just be running 93 octane but thats about it.
2. When in the 'stock' setting the unit is being bypassed altogether.
3. The driving modes are unaffected. You will just have more power to access in those modes is all. The throttle response and all of those variables involved with the driving modes remains the same however.
4. The button you are referring to is the 'reset/re-zero/sync' button. Why a down arrow was chosen for the icon I will never understand. I was explained at one point what EXACTLY it was doing but ultimately its a tool to make sure its accurately reporting and establish a real baseline. The next update to the app addresses that whole option among other things and should streamline it. At one point the goal was to implement the functionality that it would automatically do that rezeroing process everytime the car was started so it would be a non-factor. Would love to get rid of that confusing button with an icon that doesn't match. =) Switching is instant--- the boost gauge reporting is slightly delayed (1/4-1/2 second or so) as its being sent over the bluetooth coupled with the translation of that data into a visual on the app.
