Higher ECT temps after mods

This is my first post on this forum. I've been on a few others for a long time, have used this one for research and decided it was time to join. I listed my truck in my sig. I've owned it since new. In December I did the following mods.

KEM ficm tune
Wicked Wheel 2 for Powermax (ran Powermax one year prior)
BPD remote oil cooler w/ cold package, 58v FICM, water pump
Mishimoto radiator and Intercooler. New ford t stat

Issues. First I noticed truck was a little more laggy and EGTs a little hotter. Was told FCIM tune would be warmer and a little smokier. Not sure how I like wheel.

Running tow tune along with FCIM tune my ECT now runs 196-212 driving around town. 50 degrees ambient. EOT takes a while to get to 190. But will run 195-213 in same conditions. I live at 7200' in Colorado. Last week pulling 8k ECT hit 220 and EOT 223. I know deltas are different with BPD oil cooler but this seems hot for winter temps. Not running a winter front. EGTs run 800-1200 in most conditions. I can get to 1300 if I keep in the pedal on an incline.

Seems ECT used to run 188-192 pretty much all the time except when towing. I hit 222 once pulling camper over Wolf Creek but it was August and much hotter. This was with OEM oil cooler. I can hear fan once I get to 210. ECT seems to want to stay near EOT once EOT has gotten above 195. Figured they would be different with oil cooler.

Not sure what to look for. Doing all the mods at once makes it hard to trouble shoot. Thanks for the help. Levi

A couple of thoughts:

1) FICM tunes seem to drive up EGTs.
2) Your oil and water temps do seem a little high considering the time of year.
3) With the BPD oil cooler setup, your oil temps no longer influence fan operation. This can present a problem when towing heavy or at slower speeds, as oil temps can climb pretty high. One solution is to have your custom tunes (SCT) modified (or get custom tunes if you don't have them already) to include a fan set point for EOT. Matt at Gearhead Automotive has tunes with this trigger.

Also make sure your thermostat is not opening to hot. If i'm not mistaken it should open at 160*F.

ECT thermostat begins to open at 195f and finishes around 218f. Are you referring to the EOT thermostat that's part of BPDs cold weather package?

I didn't see that he had the BPD kit.

If the turbo is not functioning at lower RPMs would that make the truck run hotter. I data logged and had tuner look at logs. I do have customer tunes for the Powermax. Here were his comments.

"Looking over the recordings and comparing them to the calibration, at idle and up to around 1200 RPM, the VGT duty cycle is much higher than it should be with EBP lower than desired. At higher pedal positions over this threshold, the numbers line up with the calibration desired. This points to an issue with turbo design or operation. Is the acceleration better or worse with the race tune?"

After the mods I would have expected the ECT to be lower since it wasn't cooling the oil. Figures deltas would be further apart and EOT would run hotter. EOT seems ok. ECT really fluctuates a lot. I can go from 194 to 210 either way really fast once truck is good and warmed up.
