This might help. The sticker in your glove box might have one of these codes.
YF5 is for the CA emissions
FE9 is Federal emissions with no EGR/CAT (NF4 federal emissions with EGR/CAT aka Clean Fuel Vehicle Fleet Emissions).
NE1 is Northeast emissions this covers MA, ME, NY and/or VT. They have adopted the CA emissions package (some of these states opted in at different times, at least that is my understanding.)
VCL is Clean Fuel Vehicle Fleet emissions and also will have the CA emissions package.

GMC '04 2500HD SLE CC D/A LB7 SB Summit White, LineX, Nicktane, JK headlight harness, JK fuel pump and harness, Banks exhaust, EFI Live, intake horn mod, Suncoast 6 speed conversion, injectors at 112,265 (#8 again at 136K), ...and all 8 again at 168,368.
VW '02 Jetta Wagon TDI 6 spd ERF manual, DLC520 Bosio nozzles, Malone stage 2.
VW '01 Bug TDI 6 spd ERF manual, T-4 injectors, Malone stage 2 tuning. My FUN summer driver.
Fuel mileage? Who cares, its a diesel.
