Does any one know if a 1705 superchips tuner will work in a 99 f-550 7.3LPSD

 

yes it will, check out www.superchips.com
but why not go with the sct xcal2 for cheaper and better results?

 

Don't waste your money on a 1705. That thing is ancient. As I recall that only has 2 programs and maxes out at 80 or 90hp. If you must get a Superchips get a 1715 which has 3 settings and goes up to 110hp. It can also read DTCs whereas the 1705 can't. I would suggest skipping the tuner all together. Get a 4 pos chip from Jody at DPtuner.com. A 4 position (including stock position) is about $384 unless his prices changed. Pretty much the same as a programmer. There is no way that any of the programmers out there can hold a candle to a flip chip, let alone a DP chip. My 80hp economy position is more powerful than my Edge Evo stacked with Juice/Attitude (this combo is way more powerful than that POS Superchips). My 120hp position is flat out insane compared to the old programer.
