My first upgrades have started coming in for my 2006 F350 that I bought a couple weeks ago. The truck has about 46,000 miles, and has a clean OASIS report. I did my first service this week with synthetic oil and changed both fuel filters. I installed a Sinister Coolant filter this week and guages for monitoring my EOT and ECT. My EGR delete came in, now I'm waiting for my SCT programmer. From monitoring my temps for a few days the delta is normally around 6-8. Highest delta i've seen is EOT 197 and ECT 186. But normally it's about 194 and 187. SOOOO it seems like the temps are pretty good right now. I'm trying to decide weather to monitor the temps for a while and see what kind of stuff shows up in the coolant filter, or do the EGR delete right off. My only worry is that the coolant flush will plug up the Oil cooler, which would suck because it seems to be working right now..AND I don't want to take it apart twice if I can avoid it. I'm considered doing the flush and switch to ELC right now, then monitoring the temps for a few months to make sure they don't get any worse. I'm sure some of you have been in the same situation..just trying to get some opinions or if you've made these changes what did you have for an outcome? Thanks in advance!
