I'm ordering the last few parts I need for this years mods and wanted to know if I needed an upgraded throttle body for safety or performance reasons and do they really help? If they do which brand and where to buy, I'm also wanting new plug wires, O2 sensors and sims. I'm installing a CARTEK stage2 package with LS6 intake and upgraded injectors and run a TNT wet nitrous kit. Thanks for your help in advance. Bob
Bob,
I have modified throttle bodies on both the C5's but there was never any seperate dyno pulls and both TB's were added over the winter with many other (headers, intake, etc ) mods done @ the same time. Many people here say that this mod is worthless but mine sure does look nice to me. :D :cheers: :steering: :flag
