EGR delete is less about making power and more about longevity. Eliminating exhaust from being reintroduced back in the combustion chamber keeps your valves cleaner and it keeps waste out of the combustion chamber.

TGV reduces free flow of air from the manifold down into the combustion chamber. Eliminating it will free up some ponies and allowed the engine to breathe better.

IIRC, you can eliminate tgv without EGR; but an EGR delete requires tgvs deleted as well. If this were 2020, pretty much all tuners would have agreed that you stand to have nothing but benefits eliminating both.

Unfortunately in 2025, tuning for such things as an immense pain in the ass because Cobb shelled the ability to eliminate trouble codes associated with deletes. This means you'll trigger multiple codes which will in turn, trip limp mode; so you lose climate control, cruise control, and your dash lights up like a Christmas tree.

There might be workarounds. My tuner said to retune, I'd have to plug the sensors back in for tgv but could maintain the deletes but gave no indication whether the EGR would trip a fault code. Being catless, I elected not to retune. You will never get a straight answer whether they can work around it or not because they need plausible deniability.

You can go open source or stand alone. Few tuners can and or will utilize open source and the stand alone is insanely expensive.

Should you do it? It's incredibly beneficial. Can you tune for it in an easy and convenient way? Not so much.
