ratlover 03-20-2007, 02:57 PM If it does code get a finger stick. a EGR blocker plate is also recomended but unrelated to adding exhaust. Do a search on "finger stick" My truck didnt code with exhaust but some do :) bikerboy37 03-20-2007, 10:29 PM Any reason why some trucks throw codes and others don't ? P.S. - was reading a posting about on-star being able to "see" any tuning done on a truck .... will Big Brother be able to "see" finger sticks ??? ratlover 03-20-2007, 10:47 PM Becasue I'm better looking than most other drivers? :D I duno.....one of them things? May have some to do with my truck being a fed emmision truck? SleeperTRK 03-21-2007, 02:38 AM Mine didnt throw codes for the longest time, but now its pretty regular...I need to install the finger. No, Onstar wont know about the blocker plate and finger stick. A tuner maybe, but why should they even be looking? DURAMAX3500 03-23-2007, 12:59 AM get a finger stick/blocker plate. also does anyone know if exhaust will void the warrenty? SleeperTRK 03-23-2007, 02:14 AM Depends on the dealer, mine doesnt like my 4" but hell. I figure since I have a brand new exhaust, no CAT, and a blocker plate anyway, go ahead and void my emissions warranty :D | ||
