Okay i've heard of those grounding kits adding 5-20 hp, i dunno if its true but a lot of my friends just put grouding wires all over the place and said they could see a difference so i really wanna know if it does make a difference? also where can i put a ground at to make it better? IM? TB? Exhaust mani? where... anyone help me!

 

It adds like maybe 2whp, just the new trend.

 

Grounding kits usually ground things like the starter, alternator, engine block directly to the battery. Gains are usually minimal, but they do tend to make powerbands a bit smoother.
