That's normal for a P1 unit. I posted screen shots last summer comparing a P1x to my Whipple. Both start around 115-120 MAT then by the top of 4th gear mine is around 130 but the P1x is 154. Peak boost was similar between the 2.

Either way if you are on E, then you shouldn't need to pull any timing until 154 degrees. You can also use a little meth injection for cooling...or move up to a D1x.

Timing pull is costing you power. I believe the "more heat needs less timing" was taken out of context. It does to keep detonation at bay but it doesn't make the same amount of power as cooler cylinder temps and more timing. There is a range you want to be in for peak combustion efficiency.
