you put the supra on a very high pedestal, and seem to spend most of your time grumbling about the short comings of the zed, its like you don't want to change.
i'm all for useful discussion, but if you keep waving your supra around like some kind of wonder car, your not going to endear yourself to members. imho
for the benefit of the thread.
UK spec car, before the winter was averaging 25 mpg currently down to about 20-23 mpg this is on short journeys about 8 miles a day. this may be down to mods. long journeys was seeing about 32 mpg, currently on about 30 mpg.
hoping after a remap to see a change for the better, but main aim is for performance and torque.
i think the new spoiler has added to the drag co-efficient hence the drop of around 2mpg.
i am monitoring my mpg on my phone with a special app, so should be able to plot any changes from now and through the remap.
hope that helps
