Morning All, I finial bit the bullet and picked up a gauge kit (trans, boost and pyro) and other goodies from http://www.vulcanperformance.com/

most of its straight forward, but i have a question about drilling the manifold for the pyro,

 

who has drilled and tapped the hole with out removing the turbo?

 

also, is there a standard paint number for matching the gray trim?

 

thanks  (truck is a 99 2500 auto)

who me? LOL,, im not too worried about drilling and tapping iron, thats the easy part. i may be replacing the manifold after all, I found a crack between three and four. I may end up holding off on the pyro install

Good time to practice on the old one drilling holes.
