Just installed the Volumizer in my 600 It has 3 settings, 60-100 and stock hp. This box connects to the map sensor-rail pressure sensor- cam sensor-crank sensor. I could tell that the timing was advanced in both the 60 and 100 hp settings. Day and Night difference from the stock to the 60 hp by just the sound of the motor. I will check milege this week and post back . My overhead milege went up Quite a bit so I dont think it is correct but if it is correct WOW!

 

There's a guy that put one of those on his truck on the DTW forum. HUGE problems about a week after he put it on.

 

what kind of problems did he have??? And was it on a 600?

 

Chubby,
Mine is a 555 but after almost 7,000 miles in a little over 4 months of use, I have had zero problems and zero codes . See my gallery for dyno results.
