Pressure sensor for greddy EU, is it needed?
I got it, but don't know if I'll need it or not.

 

Depends if you want to tune with MAP or MAF input. There are several opinions on this and there have been many discussions on many threads about what method of tuning is better.

 

Fito, its needed if you have Forced Induction on your car. If you have an e-01 boost controller, then you already have the pressure sensor, and only need the e-01 pressure sensor HARNESS. I have them in stock if you need one.
