little things help
boost is the main thing to do to gain a lot of HP but there are also little things too that even though aren't that noticeable actually can help you gain little bits of hp here and there. like here's an example, things that rotate while the engine is running like the distributor, cam gears, pullys, ect. if replaced with lighter material parts parts can give extra hp. so that's one small way to make sure u maximize all the hp potential because i know a lot of people forget about things like that. and of course boost the engine.
