The boost map sensor on the boost pipe. What's it purpose? I've read some say you don't need this some say you do. 

 

I'm not looking at removing it etc but wondering if it can stuff up without registering a code? And also how long do these last on average? 

 

Have read it can stuff around with fuel economy and boost fluctuations etc 

 

Mine original at 380 000ks. So wondering if this is something people see fail over time in these cars

if the tune doesn't use it, then you don't need it, but the stock tune uses it.

Thanks. So in a stock tune does it affect economy etc if it's playing up? ....just trying to work out what it actually does and can do if failing/treading wrong but not wrong enough to cause a code yet 

I don't know the specifics... a tuner can weigh in and tell ya.

All good Thanks
