I believe the stock MAP on the GSR can read 10psi max. If i run 10psi daily and get a spike in boost for some reason the computer wont see the air coming in and wont and fuel......which will blow the motor tight? WELL ant aftermarket MAP i can get that will let me ready something like 20psi'ish for future upgrades and psi increases? BTW how hard are they to install and WHERE IS IT. thanks guys
