Has anyone done an egr delete on the 2.5 v6. Ive had a look around the bay and theres pipes everywhere and have no idea where to start?

Also ive spoke to a few places over the past few months that say they cannot map the ECU in the v6 non turbo and only one place said they could but it would be expensive because they'd need to buy a program to hack into this specific ECU, any information on this would be brilliant.
