keep EGR or not?

[tonys87]

I bought this setup from a member on this site the intake has a block off plate for the EGR..my question is what does the egr do? and how will it effect my car if i dont install it when i hook up the new intake setup. i tried searching but nothing comes up under EGR

The EGR is (Exhaust Gas Recirculation). It takes unburnt exhaust gases and puts them back through the cumbustion cycle. If you are not going to take your car through emissions checks, you probably don't need to put the EGR valve back on. The EGR controls the NOX emissions (oxides of nitrogen). If you have a faulty EGR valve or no EGR valve, this causes a rise in the NOX emissions. But again, if you do not have to go through emissions control checks or your emissions controls do not inspect for NOX, you probably don't need the EGR valve. This is a short explaination of the EGR. Hope this helps.

If you are using a TT chip. the EGR function has been disabled by the chip

EGR also helps control Nox's on emissions also for testing, don't know if you have emissions testing out there or not.

i have tt chip so that means its not even working? and from what im understanding it will only effect my chances of passing smog? i have a smog hookup so that is not a problem..
