3.9 fuel chip


Recommended Posts

I have for many years been thankful to the Guys at RPI for help with my v8's, having messed about considerably with the fuelling of said engines I remember being advised to re chip the cpu if I want to get the best out of the engine in regards to performance and fuel economy as the standard set up leaves a lot to be desired. Can I have your comments or tells of woe about doing this. 3.9 1994 60,000 miles auto piper cam petrol,lpg,hho no lamda's not cats fuel resistor changed runs well used mostly for towing allways looking for a few more mpg

Regards Steve
