What size drill bit for pyro install?
Does anyone recall what size drill bit and tap you need to install an Isspro pyrometer probe? I guess I could call but I wanted to check here first. Also, Where are yall tapping into for the boost line? Do I have to drill and tap the intake horn or can I avoid that? Thanks

if its a 1/4 npt fitting use a 7/16 drill bit. I drilled my intake horn but i think for your truck you can get a boost bolt but i'm sure someone will know for sure

I can't remember the exact size on the drill bit, but I used a boost bolt for my truck so that I wouldn't have to drill and tap the intake horn. You can find them @ Diesel Manor....
