Is this a problem?

I have an 05 6.0 with about 75k on it newer oil cooler and bulletproof egr cooler about (6 months)
I have an edge set to zero just to monitor temps
sct tuned by gearhead
so here is what i have noticed over the last 30 days boost seems to climb very fast just a touch of the peddle and it seems to be at 10psi lay into it and its over 20psi i really do not remember it boosting that fast before? On the highway at 65/70mph boost is about 7 to 10 psi is that normal?
part 2
today while highway driving the ect always floats around 188 to 194 (new stat)
now the eot seemed to be bouncing around a lot, it would jump from 196 right up to 202 then go back down to 188 I seen it in the ranges of 188 to 203 did not really matter if I was on the throttle or not. does this seem normal? it just seems to jump around and i do not remember it doing that before. Any thoughts what it could be? it was about 60 deg today.

If you are cruising along under the same conditions for example flat and no wind temps should be pretty stable. Hills, traffic, speed etc. have an effect.

When they replaced the oil cooler do you know if the screen and system was flushed? Might have a plug somewhere. I don't know that for sure but it could be a possibility. Also like PGreensvt mentioned conditions will make it vary as well. Keep in mind that those tunes do make them run hotter than normal and that is part of the reason they void the warranties.

The only thing that worries me is how the oil temp moves around so fast while driving I have seen the oil temp go from 197 to 188 at one time it didn't lower one degree at a time it's jumping up and down up 3 deg at one time then back down a few degrees.
