So I'm new to mods (been reading for 2 days) and I found some information on TB mods.... Removing the diffuser and boring out the TB to be specific. I have rearewhere some say it was great and others say it started throwing codes... I have a 2005 Silverado 1500 with a 4.3 (I know it's a sad engine) can anyone tell me if cutting off the diffuser will be good for my truck or not?
