Has anyone reflashed their 3.0SC V6 aka Tune?

[jlglr4]

Do you think the tune actually improved your mpg, or is that what you were seeing before?

Is this according to the computer, or based on manual recording of miles/gallons? ... Keeping track manually, I’ll only get 16 mpg if I’m all highway.

Ditto on this question. The trip computer claimed MPG is consistently around 5% higher than actual, despite entering the max allowed correction factor via Gap/IID tool. I track gallons added from the pump receipt, and write down the trip computer miles, to calculate actual MPG. Typically in the 15-16 range for our 2010 with V8 around town. Haven't made any long freeway trips without a trailer yet so I'm not sure what it will peak at with the cruise set at 85mph.

Are you driving it like you stole it?

also, did you upgrade the intercooler/charge air cooler pump as well or leave it stock?

I’m in a yes I want it / I don’t need it schizophrenic place with a tune right now

Stu.

I would say assertive driving; not ******* it but not out for a Sunday cruise. Highway speeds are usually 80-84

Only other mod is K&N replacement filters.

Thanks for the info. I’m sure I’ll see you in the la urban jungle one of these days.

Slightly better. Prior to the tune I was getting 15.38 with 18 fill-ups for reference.

Yea, with the app I enter milage and gallons when I fill up. If you miss a fill-up entry, you check a box and it won't factor that in to the average mpg.

And I upgraded to a higher flow Bosch inter cooler pump.

@Fuji4 do you have a link or anything to what you used? I'd be interested in doing this too

@Fuji4 plug and play, or did you have to modify the electrical connections?

Got a Mercedes wiring harness and wired that in. It’s the stock pump on amg cars.
