egr delete/plugging head question
So I did the egr delete without a tune. Been running like that since a good year no issues, but mpg did go down. Now since I have my transfercase/transmission out the intake manifold is pretty easy (well, easier) to take out. Plugging the head for the hot exhaust gasses, will I need a tune after doing this? Can I run the car as is or is there a benefit modifying the ecu that is laid out on this write up? (https://www.evolutionm.net/forums/ev...anister.html)? I live in FL so I don't have any emissions/inspections or anything.
Also, is there enough space to tap into the head while the head is on the car with the intake manifold off or can you just plug it from the intake manifold side?

How tight does the plug have to be into the head? I was able to tap it while the head was on the car(was annoying to do, I'm sure it would've been a lot easier if I had the right tools). I put mine in and fingered tight it with red loctite(not sure if the loctite will hold to how hot the egr gasses can get). I wasn't sure if you need to crank it super hard in the head, was scared to stripe or damage the thread tap I did.

If it works how I think it does then the hot gasses would still touch the plug I put onto the head thus gets stupid hot thus loctite would be useless.
Sorry for the dumb questions.

I drill and tap for 1/4' NPT plugs, and use brass. I've done like 5 now. Always wuss out and seem to not drill deep enough so I have to grind the plug down flush lol. Haven't had any issues. I get them in there pretty tight.

Yeah. Usually the steel Allen key starts to slip in the brass anyways. The head is pretty hard aluminum, I wouldn't worry too much about stripping it.
