If I supercharge my 01 se manual, will I need a boost gague? What does it do, do I need to monitor it while I'm driving? Will someone please help me. Thanks.

 

I believe that you would need one. It allows you to monitor your boost levels to make sure everything is on the up and up. Stillen makes them and also some other import vendors. You need to couple it with either an air fuel ratio guage or an exhaust gas temp gauge. this second gauge is critical because it allows you to see if you are running lean. Running lean is bad and can equal detonation and eventually a new engine if you are not running the correct fuel mixture. Throw it up on some pillar pods and it will not only be functional but look pretty good also. LOL
