Edge mileage max Vs. Quadzilla max mileage (M3)

[hobigusn]

Which is the better module? But which is the best with engine longevity in mind? Trying to get the best mileage from my truck, but don't want to shorten it's lifespan.

I have the Quadzilla mileage max and I was concerned whether or not it increased the rail pressure which I didn't want so I contacted Quadzilla. They said it only does the timing. I found it helped my mileage by 1-2 mpg but even that is subjective since my driving is different from day to day. My truck has always gotten very good mileage and this helped I think. When I started having starting issues I took it off as part of the troubleshooting to see if it had any effect on it (which it didn't) but I still haven't hooked it back up.

I go EDGE ATT. JUICE. Yes this is a pressure box. On the mileage setting i get 1-2 mpg better then stock.
