Hello everyone,

I recently bought a used 2003 Ford F-250 SD 4x4 and it came with a Predator series programmer. I'm not sure what model number or year it is but I suspect it might be from 2004? The previous owner said he bought it to tweak his transmission shift settings for hauling a trailer. I would like to be able to return to the stock settings and possibly tweak some others: rpm shift points (delay my overdrive), fuel base and maybe for 87 octane which is all I run at the moment.

I recently bought a K&N cold air intake hoping for an increase in power and fuel economy but am still running the stock exhaust configuration. I notice some hesitation when trying to excellerate along with a high pitched ringing once in awhile, especially in colder weather. I am hoping by tweaking some of the air/fuel settings that it will correct this...

Any info would be greatly appreciated, or if you know of any shops near me that might be able to help. I live near Vancouver in BC, Canada.

Thanks,

RG

Not much to it, plug it in, pick the original backup option and it will go back to stock
