To make a long story short i have an 04 6.0 auto. I had a few injectors crap out so i bought a set of +70hp injectors from RCD along with an SCT X3. I loaded the tunes and the truck didnt run right. I called RCD and after i got the runaround for 2 weeks they sent a new tune. The truck still wont shift right. As it wants to shift to the next gear it kind of surges like it doesnt kno when to shift. Sometimes depending on the speed and throttle position it will do it in all the gears. I have to either let off the pedal or give it more to get it to shift. This 2nd tune from RCD was supposed to be a garunteed fix but apparently somethings going on. The tranny shifted smooth and never had a prob until the ECU was flashed???? :confused:

truck has 138,000

Other Mods:
EGR delete
K&N intake
5" custom exhaust.

fordfreak: i will check with RCD in the a.m. and confirm the strategy matches up. They had also stated today when they emailed me the "revised" tune that they had flashed the same tune in one of thier "own" trucks and it ran flawlessly, leading them to think there is something wrong internally with my tranny??

The injectors were installed by a friend of mine who used to be a diesel tech for Ford.

And as far as i know it was never flashed before i bought the truck, owned it for almost 90,000 miles. I do however have a Banks bullet programmer still in it that i have continued to use as a boost gauge. If its non-functioning in stock mode like i have it, will that have any affect on how the SCT tunes loaded?

i have been lurking around this site for the last 2 years when i needed to know some urgent info. this site is full of great information and some great people. thanks for all the past and future help!!

Some of the trucks in 04 like mine were reflashed by ford in low mileage because of a recall issue or something else im not sure of. if it had warranty work and it had not been reprogramed they might have done it later on, but I cant be sure. Also when my truck is running higher power it shifts better with a firmer shift tune. but these guys know better then me!

yes, i called RCD and told them it shifts fine in stock mode. They said blah blah we've tested this tune and didnt have a prob, and that it might be my tranny that cant hold the added power from the tune????

Idk what to do now, these guys dont seem to have the knowledge to fix what they dont know. I have 5 unlocks left, what/where do i go???

So the shift flares bad? Most tunes will hold the gear longer and shift harder than stock, are you sure this isn't what you are experiencing?

No it doesnt shift hard at all. When it tries to shift into the next gear it seems to "surge" in the same gear like it wants to shift but doesnt know when too. I have to let off the gas or give it more to stop it from "surging" if you would. And it will do it at the top of the next gear too, gets annoying to work the pedal on and off so your truck doesnt sound like a big pos. I dont have any issues at WOT, happens under normal driving not layin into it.????

Sounds kinda like a shift flare, try a new tune, just tell the tuner you have injectors. The price for one tune won't break your bank, give Matt a try (mattr66), he is easy to work with.
