I have been reading a lot about this. For after the turbo I have narrowed the injector location down to these two spots.

How hard is it to drill and tap the stainless steel tubing?

The rubber sleeve would probably be the easiest, has anyone had a bad experience with that one?

Will the added distance from the throttle body if I put it into the tubing be of any benefit?

Am running the IAT in the stock location, although it is fast acting.

Thanks in advance.

 

just drill and tap the metal. its easy.
