for those people that have it and kno a lot abt it, is it worth the money to do it to my truck?

 

Are you blown?

 

...if so what kind of blower and are you intercooled?

 

Even if you're n/a and have a spark knock condition at WOT, meth can help. Sometimes putting on different heads can give you a fit with fuel control. If you have a way to advance timing for more power and are currently limited, meth can help get you a little more.
