Will it hurt anything, or rather is there any need to just go ahead and install a 3 Bar Map Sensor on the stock twins? My mods are in my sig. I'm also about to install my GReddy FMIC and I'm trying to fine tune my profec-b spec 2 to a Hi setting of 14psi and Lo setting of 10 psi.

Just wondering if a 3 Bar Map Sensor would help incase of a sudden creep/spike above 15psi but I'm assuming that if I go above 15psi on the stock twins it doesn't really matter even if I were to have a 5 Bar sensor?

 

2 bar is good to a little over 17psi. Dont waste your money. keep the stock one until you plan to run higher boost. Use that money for your wideband . So how was the drive home?
