Good evening everyone. I’d like to hear everyone’s input as to which mod is the best bang for the buck based on experience. I’m considering either an e fan swap (05-06 truck fans) or a TBSS intake swap on my Sierra. My truck is a 2000 Sierra with a LQ9 6.0 swap. It’s stock 317 head/cam motor with stock injectors. The truck is catless with dumped 40 series and stock air box. Thanks in advance for the input and suggestions.
