Yes here's enough metal there, I put my boost sensor in that flat spot before my truck was intercooled. Drilled the hole a bit under size and tapped it, used some hard setting thread sealant. It held 30lbs on numerous occasions.Do you think there is enough metal to tap this senor into the back of the intake? There is a flat spot as you can tell from the picture. The Ev2s doesn't use the tubing for the boost gauge. Other options?
