I just in stalled an Aeroforce Interceptor in my R55, my vacuum at idle seems a little off and I don't seem to me making much boost, can anyone tell me what it should be reading at idle?

 

-20 at idle and -10 at normal driving speed (not in boost) Without tune I can boost up to about 10 psi and a max of 12 Psi. With tune installed boost up to about 17-18psi.

 

Thanks, that's what I'm seeing. Guess I just thought the boost should be higher.

 

Nope, not without a tune.

 

My R56 sits at -11 at idle, and between -9 and -10 when driving normally. Will boost to 15 or 16 in overboost (no tune) and 12 normally.

 

lol you must have a pro sport lol

 

Yup.

 

Not aiming this at you but those are horrrrrrible...

Mine read 16.5 before a tune and that is not possible, not trying to pop a bubble but they dont. Your at 11.7-12 max during overboost if you have no tune. Switch gauges or use and obd2 scanner and youll see.


Get rid of that POOOOO!


They read wrong and amazingly delayed. When i switched to my STRI gauge i was amazed at 2 things Readings were finally correct, and the response time is almost instant for an analog gauge.


So bad i gave it away for free to a nissan guy lol

 

Good to know!
