Boost is a VDO gauge that tops out at 15- taken from the back of the manifold.
EGT probe is in the EGR plate in the manifold. EGT probe is the one that Red90 told me to order years ago when the last one failed. Wired into a Madman gauge. The EGT will go higher than 1000, I'm just afraid to melt another motor. The IP was rebuilt and ran too lean and we fried a cylinder that resulted in the rebuild of the new motor after it was installed.
She's been tuned a bit, she blows black smoke when I drive her like a V8. But no more white smoke. Thank heavens, I was so over all of that.
What I really probably need is a lesson in how to drive the 300tdi correctly and what the max RPM, EGT and boost should be given the set up and after market enhancements.
