I was having a think today (after filling up)...if you HAD to, how would you mod a Zed to improve it's economy instead of performance?
I would imagine some of the mods for performance would also improve economy, such as the plenum spacer, less restrictive exhaust, and a remap.
What else could be done?
Just a note: If you now feel like replying "but the Zed is a performance car!" then just save it. It's just a hypothetical question and I fully understand the point of buying a car like it
