I got the tgv deletes. It made no noticeable difference and I've read it losses you some bottom end.
So defo not worth it in my opinion.
If you are doing anything with the inlet i would buy the spec c manifold that Alan has for sale. Easier and i'm sure would work out cheaper.
What's the air pump thingy?

the air pump is bolted to the pssenger side shock mount it blows air through the the cat on cold start up to keep emissions down there are two valves which open at start up and close when pump switches off seems to be a popular mod in america to delete tgv and airpump both expensive fixes if they go wrong.did you get the butterfly valves completely removed when you did tgv delete supposed to be 15/20 hp gain.[ air pump and both valves cost 1500 euro to replace ] hope this explains dan

I have never heard of the air pump.
Yes the whole lot was removed. I couldn't tell any difference after. Certainly nothing worth what it cost me.
You might gain 15 / 20 bhp if you were running huge horse power but at 450 i didn't notice anything at all.
Have fun what ever you do.
