Always thought it would go away once I got the car tuned but it never did. I'm dropping it back off at my tuners in a couple weeks too have it looked at, but does anyone have any ideas?

I kinda get the same thing sometimes and just assumed its that. I always notice it doing weird sh*t in the morning when its cold. lol Link to comment Share on other sites More sharing options...

eff xr6t Member 569 Member For: 10y 6m 18d Posted 06/09/17 09:19 AM Share Posted 06/09/17 09:19 AM Was the trans tune modified? Rpm change without speed change is worrying as the convertor should stay locked at light load. 1 Link to comment Share on other sites More sharing options...

turbotrana Member 2,586 Member For: 21y 18d Gender: Male Posted 06/09/17 11:09 AM Share Posted 06/09/17 11:09 AM Had similar problem. Yes tune related but could not say if Ford induced or Tuner induced. Somewhere along the line I did something on HP TUners that solved it. Too many changes to know what I did. Basically I started from a stock tune and tuned myself. I would start by changing the Speed Density tuning maps to ones which are richer in the cruise area of the maps. In the FG the maps do vary a bit and caused me problems with stalling. You could change the numbers in that part of the map but its easier to copy and paste from a "good tune" to see if it does anything or not. Buy HP Tuners if it really bothers you. From my experience unlikely a Perth shop will solve it, but happy to say they will and take your money. 1 Link to comment Share on other sites More sharing options...

It's an easy fix Requires a couple of changes to the torque converter lock up maps. The surge is the car shifting between two or three maps and unlocking and locking the tc. 3 hours ago, eff xr6t said: Was the trans tune modified?
