Anyone know what the max psi the boost gauge will show on an 18 TTS? Asking for a “friend”

I’ve seen 19 when reality was 22

So it only goes to 19psi then? That’s interesting...

DJ23

No. In the manual it states 20 PSI. I've seen 19 on my gauge many times.
Conditions have to be just right for 20 PSI. Speed RPM's all factor in.

I'll have to start looking for 20 now. I've run 22-24psi and have only noticed 19....but at that speed.....I might miss it....

Have you seen 20psi ?

Have you guys hit the overboost button to achieve 20 psi? I didn’t think that was active in sport plus mode. I’ve only ever seen 19psi regardless what I do.

Sport Plus already has Overboost. Normal and Sport does not and you have to hit the button. I set Individual up for normal Aero and OverBoost so it’s the beat of both worlds for Drag Racing. Max boost and least drag.

Only a few times, due to speed traveling. But I can hit 18 PSI in Normal mode without even trying due to the APR Tune. To get to 20 PSI place the car in Sport Plus, start out in a lower RPM and as you
accelerate try to keep within a certain torque range (2,250 and 4000 rpm) on the Torque-Hp graph when you are in overboost. Shift up to a higher gear if needed to stay in the band. It's a powerful car so be careful. And if that isn't enough, hit the Sport Response Button, try keeping in the range I gave you, and you should see 20 PSI.
