I would like to swap out my intake manifold and tb to get a little more hp and tourque, and i did some reading and saw that the intake manifolds on these trucks (mine is a 2009 1500) are fairly restrictive.. is this true? if so what would be a good intake manifold and tb to swap into it?
According to your member info you have an nnbs 5.3 .... I've read that the nnbs intake manifold is actually very good... and many nbs owners upgrade to it
