some LB7s did come with smog controls on them. mine is an LB7 and has an EGR and came with a catalytic converter too.

Kooper - i would turn it off with Efi Live and put a plate in it. easy to reverse too if needed

So a guy could get away with running just the blocker plate for a while without tuning it out directly after? It wont throw codes or limp mode?

Yes you can run just the blocker but you may throw a code. Best to use finger stick in conjunction with the blocker plate. It's cheap if your not gonna program the computer. Which engine you planning on running this way?

An early 04 lb7 Cali. I want to delete the egr now because I already have the plate and want to save up a few paychecks to get efi live with a dsp5 switch with a couple of tunes as well as tuning out the egr function.

You'll love the EFI live. I would look on eBay for a finger stick. I have one for an LLY but I'm not sure if they are the same. I can't see why not. If they are the same let me know, I'll send ya mine for half the cost. I may still have the directions. Only used it for 2 weeks before doing EFI live.

Whatever you do, do not get the stupid lope/smoke tune. It's hard on the engine cuz it cuts the fuel on and off repeatedly. Not good for the CP3. Even thou it sounds bad ass it's not worth it.

That stuffs childish. I just want a 60 horse tune that bumps the mpgs a tad and gives me a bit more power! Will probably do a high idle tune if possible. I think I'm just gonna run the plate with nothing else for a month or so since there really is nothing wrong. Thanks!

Sounds good. Ur welcome.

So if I did a EGR delete smog would pick a fight with me ?? lol

Yes. if a piece of smog equipment is missing you will fail, unless they are morons and cant tell it is gone

with a blocker plate, as long as there is no CEL they should see nothing out of the ordinary with the engine and will have no reason to fail you

can any of you spot the blocker plate?
