superchip 1704a concern
Just installed superchips tuner in my 2005 PSD with magnaflow exhaust turbo back 4" with no cat. I understand theres a "learning period" for tuners/ modules but in superchips manual didnt see one. I drove it for about 200 miles before full throttle in level 2 economy mode. The truck accelerated hard and shifted then acted like it was dying. Is there a defueling mode in the tuner that caused this or something else? This site is very cool....lots of knowledge and good info

-Make sure EBP sensor is not bad
-Perhaps there is an issue with your tune, or with the vehicle.
-If all else is normal, call superchips for an RA....they can get-er-done.

Thanks for the response........Forget to mention i am a first time diesel owner and love the super duty...When i said the truck "acted like it was dying" i mean the fuel seemed to shut down and the truck stalled. I just let off the gas and slowed down and it seemed to shift and accelorate fine. I did not try wot throttle again.....Dont know if it matters but i just took off an Edge/Attitude because of bad press and the way it shifted. Had it on for about 2weeks. Does the supertuner require an adjustment period like Edge and other tuners?

Mine works fine right after the installation of the tune.
For example, I set the truck to stock and then made a couple runs at the drag strip to benchmark the stock performance. Next I loaded the HP tune and made two more runs with no other driving in between. The truck shifted fine.
Any time I've loaded a tune, be it tow safe, econo, or HP, I've never had any learning period performance or shifting issues.

Mine is doing the same thing since I got it back from Superchips after the latest flash they had to reprogram it. I was towing my boat and passed a car and it fell on its face, let off the pedal and it was ok. I havent had a chance to try it back in stock mode since that happened. Also when pulling my camper going up a slight hill at around 50 mph light throttle it makes a strange sound like the air is going back into the air filter from the engine and starts bucking.Let off the pedal or downshift and it goes away. This is in tow safe. Put it back to stock and it runs fine. Havent had time to call Superchips. I am about ready to send it back for a refund. I dont think it runs a lot better in anything but HP mode and it smokes to much in that setting (tires and exhaust) I dont mind the tire smoke as much as the exhaust smoke.I had a microtuner on my 7.3 and loved it was why I bought another one.
Yes there is a rev limiter but I was only going around 50MPH when passing and was no where near the rev limiter I think.

I also have an 05' PSD, love it- (except for the rough ride on cement freeways here in CA) no problems from day one and have been running it hard with the SuperChips in HP mode almost all the time. I have not had any problems with "dying." When mine shifts at WOT the tires chirp till hitting the 3/4 shift. I know others who have had minor problems, but mostly due to a slight error when loading the program. Just remove and try to reload and see if the problem continues. Good luck

I would definitely list the concerns and call Superchips.
What kind of issues are you having?

mrcobra 350..... mine does the same thing that yours does.... on the highway coming to a slight hill it starts to buck and seems like the waste gate or something is opening for a split second..... it gets worse until you make the tranny shift down.... as its bucking i notice the turbo boost gauge dropping right down to zero..... this is worst with hp setting on the superchip.

Make sure you have the latest flash from Ford. If you do, and it is still doing it, then consult Superchips IMO. From what I have seen it is a stock programming error, even if it is only evident with the SCMT installed.
