JCyrbok,
I have, as far as gauges, the same setup as you do. My gauges are not really working up to snuff. Both EG Temp gauges went out within 4 months of each other. Both read max temps. The trans, rear diff read good. I trust them. But I don't know if its the voltage amplifiers or the probes on the EGT gaugues. SPA does not sell the 1/8 probes anymore. Yeah I can source them on the net, but I never did ask questions to SPA. Maybe I should. I also have the Dakota gauge also. Never has failed me yet.
Talk to James Northum today... . getting ready to put DTT in my signature...
I guess I stole my own thread for something else... oh well... its all good...
