: Finger Stick required on LB7? downsouth 07-19-2006, 11:21 AM I've got a quick question for you guys. I've got a 2003 LB7 and would like to install an aftermarket 4" exhaust. My question is am I going to need the fingers stick and blocker plate with the LB7 motor if I go with the cat delete? I thought I read somewhere before that the cat delete wouldn't give any codes with the LB7 motor but I just want to be sure. Thanks. briano 07-19-2006, 11:51 AM more than likely, no. McRat 07-19-2006, 11:55 AM Blocker plate is for LLY EGR. Finger Stick is LLY only. You're good to go. downsouth 07-19-2006, 03:53 PM Thanks! WanaDmxsub 07-19-2006, 10:35 PM Just a note; '04 LB7's with EGR's could use the blocker plate (All) and finger stick (Cal only). Problem...Finger's doesn't make one for the LB7. I know...he has an '03... dodavison 07-20-2006, 03:46 PM If you get a code the LB7 can be reprogramed to eliminate the condition that set the code so I am told (I think they use an EFI programer). Some don't get a backpressure code by taking off the kitty and muffler. WanaDmxsub 07-20-2006, 10:34 PM The Back pressure code is LLY's only, not LB7's. If you disable the EGR on a CAL LB7 you will set code. EFI should be able to but I don't have it so I can't say forsure. | ||
