i have a 2004 f150 with the 5.4 im looking at getting an edge products programmer i was woundering if it was still okay to add this when my truck already has 90,000 miles on it???

 

I put my programer on with 124k and had it on for 20k since then and no problems.

 

If you dont have a warranty go for it. If you have an extended warranty then I would think again. I have thought about getting one also but my warranty has already saved me enough money to not want a programmer to void it. My 05' just rolled over 100,000 a couple of weeks ago

 

I just put one on mine with 180,000 miles. So far so good.

 

I too have always thought about this issue. I have 85K on my 2005, and wondered if using a programmer would cause some damage to the automatic transmission; a tuner changes the shift points and/or firmness of the shifts. On a transmission with mileage, I've wondered if this was a good idea to do this. It is always a good idea to have firmer shifts if you want a transmission to last, as firmer shifts replace slippage (softer shifts) and therefore reduce the wear caused by soft shifts.

I've always taken care of the ransmission (it's been flushed at 60K, and has a trans cooler), but I still wonder if it's a good idea to make firmer shifts to a transmission with some mileage on it.

The two testimonials are good to know that they had no problems. I'd prefer to get more before I'd go further with the decision.

 

I put a programmer (edge evolution) on my FX4 5.4 with 86K miles 2000 Miles and $3000 later had a new transmission (warranty repair) but I will not say it was the evos fault just purchased the truck and think there was an underlying problem started to have a weird squeak when it shifted a few weeks after I bought it
Just something for you to chew on befor making a decision

 

i have 160 on mine and put the edge in. seems to run way better. the tranny used to shift kind of hard at lower rpms from first to second and now its perfect

 

I put mine on at 115k after i bought the truck at 134k now and have not had a single problem on mine and I have a lead foot that loves the sound of tires squeeling.

 

In my experience, especially with these newer electronic things on these trucks, the programmer usually doesn't cause any problems. I put my programmer on at about 50k miles and now with over 100k, still no problems.

 

i now have had my edge for about 6 months i love it it makes my truck alot more enjoyable anyone thinking about going with a programmer go edge evo
