The EFI engines don't like it when you get rid of the EGR valve, unless you add a bigger cam or something so it pulls better vacumn. I tried deleting the EGR on my truck when it went out and it ran like dog poop. Its mostly in the programming of the computer though, its made to work with the EGR. It doesn't really rob any power though, I just kept mine it was way easier and cheaper that way haha
Since you have carb you have essentially unlimited tuning option but I'd highly suggest getting rid of the original carb if you want anything better. The motorcraft carbs aren't known for being all that stupendous. You'll need at least a 600 CFM carb.
uh no. the EGR is not gonna affect how it runs.. I've deleted egr off multiple trucks, stock, mild, wild, no negative effects before and after really.
and to delete all of it is simple.
