Filled up today on return from Akron gunshow. Got 27.2 mpg on this tank of fuel, running about 67-69 mph. Been running the Painless module in E (economy) mode since install. Normally get about 25 mpg during the cold/cooler months. Maybe fuel blend change? My buddy believes the engine is quieter on the road then before. I really cann't tell as I am somewhat tone death from artillery(USMC) and too much handgun range time. Haven't tried any of the other modes yet. :evil:

Next test would be without the Striker to see if the mpg drops back to 25. We were getting 22.5mpg hwy for the longest time.
I did the ORM and it jumped to 24.5. I then added the DS cetane boost and it jumped to 26.1. This tank is without the DS cetane to see if drops back.

I think they call that ABA testing. I would rather just reflash the ECU, but I can't do that just yet.

Making a trip to Knob Creek, KY next week. Will try running stock mode vs E mode. :evil:

I have I Dr.Performance, It plugs into both the MAP and Fuel Rail. I automatically got and extra 2-3 Mpg. Well worth it! I don't see a huge performance difference but there is a huge midrange torque difference, Transmission hates it if I dial it all the way up(slipping and shuttering). I think the chip would perform better w/o the F37. I think it is putting a hurting on trans now that I had the F37. ( I did not have chipped before F37, got afterwards! )

I saw a 2 mpg increase running the Workhorse (same as the Dr, Performance) in my Cummins.

so you have said twice...but really who cares? The real question is how the Jeep Liberty CRD does with it.
