Now not such issue. Also a clean EGR and manifold helps the car breathe much better, aiding responsiveness.
Also, try with the EGR vacuum line blocked at the EGR valve (if you still have it). The difference in responsiveness was marked in my auto diesel. Don't just disconnect as this is the same line used for the brake servo. 
Lastly, try using D3 to hold onto gears, then change to D4 when ready, then finally put in D. The car will accelerate more cleanly as it is not trying to change up and you are control. |
Thanks for all that, the maf is good according to Phil's t4. I recently cleaned the egr, and disabled it by blocking the pipe. I also did pcv filter, and intercooler o rings. Apart from the atf, the car is fully serviced and working as it should.
I do like the way the car drives, and when its on its own, it does seem to pull quite well, certainly better than before the remap, but like I said, I was just a little surprised at how much power the auto box loses, when compared with a standard power, manual version.
