how to make power
#3
LS engine swap, done.
Or the hard way. Dump the useless factory intake manifold for the $800-$1000 marine version that gets rid of the spider arrangement and gives you external rails and injectors.
Then cam, head work, long tubes, full exhaust ( factory duals to the muffler and manifold are the largest restriction on those trucks versus the muffler and tailpipe), swap to 0411 PCM to actually be able to tune it....
And spend more than swapping a good running 6.0 liter into it to still have a truck that gets skull drug by said 6.0.
If you truly want just a little and nothing major.
Long tubes and go with at least 2.25" if not 2.5" piping back from there. Outfits like PCMforless have the Tunercat software to tune the old black box PCM you have.
The black box pcm's are limited to 5900 rpm no matter what..... but your intake is killing anything about about 4000 rpm so it really doesn't matter. There is an intake spacer made that is supposed to help ( not throttle body junk, lifts the entire upper plenum and is called the Vmax)..... I had one for my 96 but never installed it.
Good luck.
