romping when hot
got a 2000 7.3 in the shop just finished a lot of work to it 8 new AC code injectors, bellowed up pipes, wicked wheel in turbo, fuel pressure spring mod, new high pressure oil hoses and cross over hose, 203 thermostat, glow plugs, wiring harnesses, new oil and filter, fuel bowl reseal. came in not starting without block heater, skipping and leaking at up pipes. now after all that work it romps when the temp gauge gets just off the cold mark and then gets worse the hotter it gets. cranks and idles prefect cold. and cranks back easy when hot. any ideas ?

Out of curiousity, are you running those AC injectors on the stock calibration? If not, what tunes are you running and does the issue occur in all settings (assuming you have multiple calibration choices...)

where do you get that from. I'm kinda new to turning up the powerstrokes been working on them for years but mainly just repairs back to stock and some minor upgrades. I'm well versed in the IDIT performance side but this is the first guy who wanted me to turn his psd up. I have a sct tuner on my excursion would something like that work. or does it need to be custom programming.

Most folks here use DP Tuners, Gearhead, PHP etc. There are quite a few choices. If you search some of the tuning threads then you can find out who many of the vendors are that offer the service.

Good choices. I personally would rather have fuel pressure vs boost strictly for diagnostic purposes. If the owner tows heavy and has room for only three gauges then engine coolant and EGT are good choices and then get the Aeroforce Interceptor Scangauge for the third spot. It can accept two analog inputs so you can use one for fuel pressure and be golden. Then you will have other choices as well, such as trans temp, engine oil temp, ICP etc

If he is already planning on purchasing tunes and gauges....
Then DP has a cool product called Infinity that you might want to look at. It uses a Dash Daq display and has the ability to run custom tunes.
I think PHP has something similar as well. I can't remember the name right now....
EDIT: Here are some links.

It looks like PHP is discontinuing their product....Looks like the DP Infinity is your best choice because it's should be supported for quite a while. I've never used the Infinity nor do I know anyone who has but if I was going to design a dash mounted display that was able to function as gauges, run a custom calibration as well as include diagnostic tools then I'd start with the Dash Daq and build on that hardware. That one item could function as your custom tunes, gauges and a diagnostic scanner. Fair price when you think about everything that you get in my opinion...
