GM/Chevy Duramax 6.6L LLY Full Delete Bundle | 2004-2005
The 6.6L LLY Duramax Full Delete Bundle for the 2004–2005 GM/Chevy Sierra and Silverado 2500/3500 permanently upgrades your truck to run without the factory emissions system. Once the delete tune is in, the emissions codes stop — "See Dealer" codes, check engine lights, "Exhaust system service required" alerts, and limp mode.
The bundle lets you remove all the emissions parts and sensors for good — the DPF (Diesel Particulate Filter), DEF tank (Diesel Exhaust Fluid), EGR system (Exhaust Gas Recirculation), and CAT (Catalytic Converters, including the DOC and NOX). Custom delete tunes wipe the emissions programming from the truck's computer; you plug the tuner into the OBD-II port and follow the included instructions.
The box includes an EFI Live tuner with all required accessories and a rotary switch for power levels, a 4" full exhaust system, and a complete EGR delete kit, with an optional muffler available. The DSP5 switch gives you five levels: Stock at 0HP, +40HP, +65HP, +100HP, and +130HP. The EFI Live tunes are not preloaded — after you buy, they're emailed to you, and you load them with the free EFI Live V8 software on a Windows 10 or 11 PC (no Macs or Linux).
This fits the 2004 and 2005 Sierra/Silverado 6.6L LLY Duramax 2500 and 3500 in all pickup trims and box lengths, but not Cab & Chassis. No welding is needed — the exhaust and EGR kit are bolt-on, and most owners report a 5 MPG gain on average. The EFI Live is built to order and non-refundable but replaced if faulty, exhaust and pipes are final sale, and the EGR kit returns unused within 30 days.
For off-road/competition use only.
