I have an automatic 2.8 Cherokee and am getting 16 mph. Any idea how to improve this? The red "tuning" light comes on occasionally. Please any help would be appreciated
Hi Mike, what is the factory claim for MPG for this engine? I would have thought that getting the head gas flowed would increase power and economy at the same time. It depends really on how much you want to spend improving the economy. Have you read the tuning for MPG article we published? http://www.torquecars.com/tuning/tuning-mpg.php
