Will I need a different intake to make 450hp
Definitely get a FAST intake. I did mine nearly 6 years ago now and hit the #s in my sig. I felt like the tune was pretty spot on and have had no issues with it in 6 years. Did 3 pulls and that was it. The FAST, as stated, is good for ~20 RWHP on a good H/C setup.
PRC 5.3L Heads Stage 2.5
Torquer V3
Ported FAST 90
Kooks 1 3/4" LTs with Kooks Catted Y at the time and GMMG Catback. (Now duals dumped.)
I believe with the true duals dumped or cutouts on my old exhaust setup I would have hit 450 RWHP through the stock 3.42 geared 10 bolt.
