I recently installed my egt probe. We used the hi temp threader on the egt bung and sensor in the threaded header. Bought new gaskets and tightened them all to spec. I checked all my hoses and everything. We keep just trying to re tighten the bolts, but I am not hitting peak boost. I think my header is leaking or something. Checked it to see if it leaks, but it might be so minor that we don't notice or i might have a very slight leak on my hoses. I have no idea. My boost gauge usually reads 19psi or so, but now it's only reading 16 psi. Anyone got any ideas?
