Hey guys,

I was wondering what are some good tunners for a lifted 5.4 2003 f-350 xlt? It has a k&n intake and also a dynomax exhaust and throttle body spacer if any of that matters. I just bought the truck and believe it had a tuner in it but the previous owner kept it. I also would be using it for a little bit for towing when the racing season also starts up. Any good suggestions?

 

SCT from 5-Star with 5-Star tunes. The SCT X4 comes with 3 canned tunes, but buy from 5-Star and you get 3 custom tunes for just $30 more. This is the best bang for the buck
Another tuner who is good at getting the most out of Fords can be found here:
SSi Tuning Forum - EcoBoost , F150, SHO, Explorer Sport, 3.5, 2.7, 5.0, 6.2, 4.6, 5.4 - Index Calling him on the phone, even weekends, gets the best results.

 

Give us a call we can wake that thing right up. With your bolt-ons and our tune you should see some good gains over stock.

 

I'm also looking into a tuner for my recently aquired 2006 KR with the 5.4. Interested maybe in the SCT livewire. I had an SCT on my 6.0 PSD and was pleased with it but I like the idea of a display to monitor the engine.
What all parameters can be monitored?
Do I need to get an intake and open up the exhaust also or is that over rated?
