unplug egr

[northernstroker]

Can you unplug an EGR valve? Any performance gains or will it throw a engine code?

[SCUFFY828]

it will alow egr not to work, which some would say is a gain, it will also give you several codes , p0401 , p0404, p1335 , p0403 or p0405 , at least 3 or so of those codes and cel all the time, in my opinion its a waste to unplug , there is also those that will say just get a tuner and shut it off , no codes that way , BUT if you already have a weak egr , shutting it off with programming still does not eliminate the boost levels or exhaust pressure from forcing it open, seen it many times , so with that said , here is my opinion and it is strictly my opinion but it has worked on many a truck for me

take the egr valve out , remove the o-rings and gasket , clean it good and if you cant do it your self , have it spot welded shut , make sure is closed all the way first , reinstall o-rings , and reinstall, will eliminate any egr concerns , but will give you one or 2 codes in memory , but no check engine light on , this way works best with the egr block off at the back of the cooler , elimnates heat and exhaust gases in egr cooler , i think the 2 together is the way to go , but like i said , thats my opinion, someone else im sure will have theres

I have had my egr valve unplugged since spring, I get no engine lights. I does seem to spool a lil' quicker.

is there any advantage to buying the blocker plate it is fairly cheap?

I have mine unplugged. Even when I had VXCF9(with out tuning) I had it unplugged.

faster turbo spool up
Less smoke out put
lower egt's
increased longevity of the entire engine

Some years and flahses have issues.

If you get a block plate for the egr cooler you may get codes but tuning can help with that. I have not gotten a straight answer but tuning supposedly can keep EGR codes from coming up .

The block plate makes a MAJOR difference

Just to enlighten you on what smokersteve is referring to is, with certain stradegies on certain year trucks, when you unplug the EGR valve, it prevents the VGT sweep to cycle at idle. The other issue is, it may prevent your clutch fan from reaching full RPM.

just to be sure you are talking about the simple alumium plate that goes where the EGR is not the whole bypass

Smokersteve is talking about the blocker plate that goes where the erg cooler gets connected to the exhaust up-pipe.
