What can I expect from going from a 75mm factory ported TB and factory 3 bolt 75MM intake to the 90mm stock trailblazer TB and LS2 intake on a slightly mod'd 5.3L? Will my low end be compromised for upper rpm power with the ls2 intake? I dyno'd at 303 rwhp and 307 rwtq before my last tune. I think that I might be a little above that however I am trying to move a Z-71 crew cab.
