2005 silverado dbw throttle body options. Hello all recently swapped a cammed 6.0 in my silverado that is my daily and was wondering what my options were to increase my throttle opening size. While tuning I’ve noticed past 4000 she’s struggling to breath and want to fix. I’d prefer to keep dbw. I am a capable individual with efi live and a laptop and don’t want to mess with cable. So far I’m coming up with tbss intake nick williams throttle body and x link. Those things are not cheap and while for the performance if I must I’ll do it just wondering if there was another alternative. Thanks any insight as long as constructive is always appreciated

Really...? What size cam does the 6.0 have? I doubt the intake is a problem. Check this out. https://www.hotrod.com/articles/20-l...ifolds-tested/

I think your camshaft is the cause of weakening above 4000 rpm. I bet it has goobs of low end grunt though!
