Hey guys just got my new truck tonight, its a 05 Harley davidson f-250. Mod to it are SCT tune (i believe canned tunes), ARP head studs, AFE cold air, 4in turbo back exhaust. I believe this is all thats done to it, It has a quadzilla monitor on it with an egt sensor and was driving it tonight on the highway coming home at about 70mph its making 7-9lbs of boost and egts are from high 700-mid 800's is this ok? Also wide open from about 20-60mph they will reach up to high 1300's, dont know if this is alright either. So far im in love with the new truck, have a sinister coolant filter thats going on this weekend and will have my blend mount for the scan gauge II here tomorrow.
EGT's?

Those are fine imo
Ok thanks, so I hooked up my scangauge today while driving around and watched the eot vs ect tell me how these numbers sound. 40-50 mph ect 192 eot 195, 50-60 mph ect 191 eot 199-200. Those are just approximate and I was driving for about 30-40mins. Also FICM volts don't drop below 47v from turning the key on to driving for that amount of time. While driving the FICM volts are 48-49.5 the whole time. Alt voltage is 11.5 koeo then start it and it'll read 12v for a little bit then hold 13-13.5 the rest of the time. Anything I should be concerned about?

For sure. You are going to want to see 14.1 at the battery with a volt meter. Your obd port will drop a couple tenths so 13.8-13.9 will be expected. Get that alt replaced and be sure you have good ficm voltage or you'll be changing injectors too.
Btw, your egt's look good. Only run over 1250 for short runs, not towing.
