So here we are again just like before when I turned to Superchips..No Brian(Sohfast).. and no support?

Brian are you there? In the latest Tune files I am having acceleration problems at highway speeds. At 70 mph if I punch it to the floor it downshifts and begins to accelerate as usual, then it up shifts then downshifts then upshifts again. It does this several times so I have to just let off the ...

Hey no answer on this post yet. Anyone there?

Mike, the difference in the "feel" of the tune is the power or fuel is not as linear as before. the new 100 hp tune seems to be just all out fuel dump

I am asking for an analysis of the newly written 9r03 100 hp tune file and find out the differences from the previous tune before I had my tuner sent in to you and upgraded. The new tunes are costing me $20-$30 every tankful. Where is SohFast he can fix this i am sure

how new is the 9r04 thought that was just an update for a cal id missed in the 03.
I noticed the fuel in level used to always say 100% and now they fluctuate.
So why the huge mileage difference?

I have a 7.3 l and was getting 21-22 mpg highway and 17-18 city. Now lucky to get 18 highway and 15 in town. Whats the deal? I have noticed the fuel has been decreased to 80%. Is this the reason? Or was this just done for stacking purposes.

what does the Base NOV parameter do and how is it to be adjusted?

Oh also the other morning it was -5 C and forgot to plug it in that night and it cranked right up. The batteries make a huge difference. It has never started this good the 3 years I have owned the truck with the stock batteries(750 cca) in it.

Anyone else have 7170 9R04 cold start issues??

Brian M is actively working on my issue, if there are others out there, post up. More data for Brian will translate into a broader solution.

Currently too cold in Colo to test ( and still get to work), stock tune loaded.

jammer

Nope. No problem ...

oh almost forgot, the reason I am concerned about fuel pressure is Ford warned that somehow fuel pressure can be delivered that exceeds the maximum. Could the max pressure of the pump be more than the lines will hold? Will someone enlighten me please.

fuel pressure or line pressure for the tranny? My Cal ID never changed when the dealer installed the new pcm. I have the old file which I think was better and I have the new file. Does it matter?

oh also what do you mean "fine line" of stacking?
