OMBS,

Welcome to the TDP forums. I 'T'ed into the wastegate hose when I installed my SPA DG-111 over 2 years ago.`The boost reading thus obtained may be a few psi higher than using a post intercooler location, but it doesn't really seen to matter.

See More Power's Pyrometer Installation article (http://www.thedieselpage.com/members/drillman.htm) for installation help on a pre-turbo install. A post turbo install in your ATS exhaust is another option. Post turbo EGT readings will be lower by a few hundred degrees when compared to a pre-turbo manifold probe location.

FYI, relative to the etiquette thing, many consider typing in ALL CAPS as YELLING :mad:

Not a punishable offense by any means... tongue.gif ;)

Make sure if you tap into the wastegate line that you should use brass. The hose from the waste gate is larger than the boost hose. I made a tee using one smaller barbed fitting and 2 larger ones for the waste gate hose. Used a 1/4 inch brass fitting with 3 holes 90 degrees apart. Got the whole assembly from Home Depot but a auto parts place could be better. I had to do this from scratch because the plastic tee melted.
