Hi...i am a new user here. In my case issues were there with EGT gauges. The first unit I usedwas shocker for under-reading . The second & third were the SAAS gauges, OMG, whats pieces of shit.Mine were bought from loca Autobahn who also told me the same line, no issues with them. First unit would randomly go all over the place and scared the shit out of me when it went up to 900° while on the highway. Gauge was swapped out after excuse like above was given. New one worked for a week then fark me, again, rock-show.
