Hi again! Had a word with Peter about the lagging and decided that the only way to really check what's wrong is to add both a fuel pressure gauge and an Air Fuel ration gauge. I've ordered them from Amazon and E-bay so hopefully I'll get them in the next week or so. I'll have to add a boss to the exhaust pipe next to the current lambda sensor to take the second sensor for the AFR gauge. Should then be able to check what happens when foot goes heavily to the floor.
I'm also going to add an ABS sensor over the winter so the ECU gets a proper speed signal instead of the one from the diff sensor.
The weather is still pretty mild, hopefully 10oC and sunny over the weekend. It would be great to get a little closer to the problem before the season ends - start next season fresh and healthy!
