I have a 2006 silverado RCSB with the 5.3. Currently have a intake Texas speed long tubes and ory pipe with 3 inch QTP electric cutout right behind the y and full 3 inch exhaust. Now looking into the PRC stage 2.5 heads and Texas speed cam with a stall. But was wondering what other stuff I could do to it for more power. This is first truck I've seriously done performance on and it's getting addicting lol. Also want to get a transgo shift kit. But any other suggestions for power are greatly appreciated or a thread showing what works on my 06 thanks in advance

 

I would start with a 4L80E and a stall to match the cam you will be going with and then get into the power after
