Thanks, during the shake down driving the last few months I have been using both EEHack and Scan 9495. Both have helped me figure out issues with external components. My package is pure stock with no component or engine mods. Thought it would be better to get the base system working good first. My temp readings have been very stable from cold start to running temp. With that said my fans are controlled separately via a Flex-i-lite variable temp unit. Fans come on at 195 at 60% then up to 100% speed at 200. Could that be an issue? Running down the road temps run on the thermostat(190) so I'm seeing 188-192. Could that be an issue?
