the oil temp gauge is off about 40*f and the trans temp is off about 25*f, the gauges are just a 3 wire set-up, +, -, and serial data from the ecm,

if you compare the data for oil temp and trans temp they are way off

has also happened to other camaro's i tuned,, i think most people wouldnt notice it if you were not watching the scan data while looking at the gauges

the data for the gauges comes straight from the ecm serial data line, something changes after flashing with hp tuners and the gauges no longer read correctly,, i was actually in contact with an engineer from GM and he has seen this issue before with aftermarket tuning software
