My egt's are getting a little hot and I'm thinking I need a little more air. How much power can the HX40 support? Thanks Jon

about 450, anything more and egts would be outta the safe range.

John porterfield Sr was well into the 500's and ran high 12's with one but he also had a cam. This was several years ago though.

My PDR works really well empty. My last dyno was 450/753 with a TST/Superchip and non-pop tested Jammer 3s. With my current setup I hope to be 490-500 cause the truck feels faster than before. When I run it hard the temps dont really go much above 1200.

BUT.... Once I start towing it gets pretty hot, but it might of been cause I was still running a COMP tune.
