All of us search and search on programmer info so lets put it to rest!!!

I have a 98 4wd,5.4L, 3.55s and 35s. I dont offroad just pull a landscape trailer some in the summer and only drive about 30 miles round trip to work. I dont really see alot of power loss going to the 35s. The only difference Ive seen is it takes alittle longer to go in to OD but, when Im pulling I dont use OD and the speedometer is off a bit.

I do have the AirRaid with the PowerAid spacer but lets be real, that doesnt do alot either!!

Soo on the Programmer talk, U guys with the programmers, are you "really" seeing a "big" difference or are u justifying the Money?? Lets be real these trucks(4wd) never had alot of "hotrod" power... Mind u I Love My Truck and its the best and well made but no HotRod!

Feel Free to chime in. Any commit is welcome because I know everyone is sick of searching and searching and searching
