Shorties are great for high end, maybe a tad low.
Longs, great for low and entire power band. You will also get the highend as well.
it all depends on your truck and application. no two are the same. some people can slap a set of headers on and be in perfect a/fr range. others way off.
When i installed my headers i figured i would be running lean, instead i was running way rich.at around 3500 rpm up i was losing major power!
best thing to do is just have your a/fr checked after installing the headers. it will atleast give you an idea of how ugent you need tuned, if any at all.
how much is a tune
Yeah I have heard stories of a lot of people running lean with LT headers, I also ran rich though. Uprev is $500 and you get a good custom tune after some data-logging, but your talking about a truck that is almost 1 second faster with those 2 mods. And believe me, a second is a lot faster. A truck length or 2 is about .2, so imagine how much faster .8-.9 is, which is about what you will gain with headers/uprev.
