Installed CTS just one or two ?
Ok so this past week I received and installed my CTS I ordered from ID. It went on well and even adding the EGR probe wasn't too bad. (I am a newbe at automotive work as my parents opinion is just take it some where and have it fixed) I just have two question. While running down the highway at 60-65 my EOT and my ECT have a 9* difference. Sometimes it will range from 2-12* when getting going or just putting around town but on highway I have a 9* difference. My questions are is that bad. Right now my truck is stock except for a muffler delete on a stock pipe.
So should I do my coolant flush now, add a coolant filter and keep the EGR and Oil cooler in till I get a 15*
Should I just say this is a large enough difference and pull the EGR, add a BP, new oil cooler, and then do the coolant flush before I get a 15* difference?
