Losing boost while towing

Hello,

So yesterday I was towing an empty trailer. It weighs roughly 3,000 lbs. On flat ground it was fine and up to about 19psi. Once I went over 20 psi it would run for a little then drop down to 15 ish psi and lose power.

Egt,oil temp,coolant temp,ficm all good according to my cts when it was hhapening.

Truck has egr delete, new cold side turbo tube, upgraded boots and clamps on boots.

Was running 65 hp tow tune on my x4.

Where do I start? It seems every time I tow anything I have problems. It's getting old!!

Truck also had entire coolant system flushed and oil cooler replaced. Differential is roughly 6 degrees while towing.

monitor your boost, ebp, vgt, and maf to see if anything weird is going on.
