In the 80HP tow tune, I have no issues with EGT, I think the highest I have ever seen (long 7% grade at ~70MPH slowly losing speed in 6th gear and grossing ~14-15K) was about ~1,175✯. My truck has the Donaldson AIS intake, 4' exhaust with the Banks 'Power Elbow' that completely deletes the EBPV valve and removes that choke point, and a Wicked Wheel II compressor wheel in the stock turbo and a shortened waste gate actuator rod.

The main reason I dropped the money on the Hydra was the switch on the fly capability and the ease of installing custom tunes since I eventually want to put some 'hybrid' injectors in my truck to replace the worn out stockers (256,000 miles). The power doesn't seem much different between the two though. I basically only use four tunes on it (80HP daily, 80HP tow, No start, and high idle), but the switch on the fly aspect is so much nicer than the Super Chips Micro Max 1705 tuner I was using before (my cousin gave it to me for free). I have the Hydra with the standard PHP tunes on my mildly modified 2000.
