Hi,

I've been noticing over the past couple years that sometimes when I accelerate, there's a slight delay between the time I press my foot down on the pedal and when acceleration actually happens. From reading other threads it would seem that the most common fix is to re-flash the ECU. I bought a DiabloSport Predator tuner along with a CAI a while back to help improve performance/gas mileage and I was wondering if there's a way I can use the tuner to re-flash.

If not, do most ford repair shops already carry these? I don't want to spend the $400 to buy a flash programmer. Also, if the shop does carry this type of an item, what is the average cost to get it re-flashed?

I own an '04 F150 XLT 5.4l.

 

You should try to drive a F-150 with 5-speed manual - that hesitation is intensely annoying. You pop the gas pedal during downshifting and nothing happens. You go to accelerate without shifting, say in second or third, and the throttle plate slooowly opens. Add to that VERY 'notchy' shifting and I think I'm getting ready to admit defeat on the truck and find a mid-size truck with auto.
