[jlehr25]

i have a 89 ford mustang with 2 narrow band o2 sensors on it and i was looking at either the one from fuel savers

or this one from dc hybrids

which one would be better and more precise?? i was thinking the one from dc hybrids because it looks like it would be easier to tune what do you guys think?? any help would be great

I've worked with Mike at Fuel Saver for years, that EFIE is easy to install and works great on Ford spicially those four wire narrow band. Make sure you get the wiring diagram from Mike and you have the correct wire. That late model Ford the front sensors are on a seperate bubbles. also, make sure you watch the video from Fuel saver it will help you determine the wires. this is because some of the wires Ford used are the same color for other system on the car. Knowing how to read the MV's will help. I installed a system on a Mustang but with extender, not for mileage but for extra power and fast accel.

I have a better system than that, but in 3-4 weeks from now I will launch some products 100% compatible with the one you recommend at a cheaper price. The whole spectrum will be covered (narrowband, wideband, single and dual), The price will be 10-20% less.

do yours carry a 1 year warranty also?? if so how can i get in contact with you because i would like one now not in three weeks
