EGR block on 4.6

[darkside]

Anyone done this? particularly 96-98?

I did on my 96 cobra, I just made a template from the EGR plate and cut a block off plate out of steel at work.

I've already ordered a block plate from Jeg's.

I'm wondering, how is the car gonna react to this? It's throwing CEL's for EGR, And since the delete plate is a fraction of the valve and any related sensors, i've decided to take this route. just wondering will it need a tune or what to run right?

[rtusnake]

It will run but the cel light will always be on unless you turn it off in the tune. I always delete the egr on my cars, cleans everything up

[darkside]

Yeah, the car needs to be tuned anyway due to the Rear o2's. Buddy of mine does tuning/Dyno at his shop so he can handle that.

but will hp/tq/fuel mileage gain, stay same or lose?

[rtusnake]

You will lose some fuel mileage. I believe around 1-3 mpg

[darkside]

That's not too bad.
