All this research on weather or not to get a fuel management system when I put my Big Radius pipes onfor my 2007 Fat Boy is driving me crazy. Now I call this place in Denver (Roadies)to ask how much it is to get a PCIII installed and he says the Thundermax is the way to go. Seems the PCIII installed is $700 with dyno tuning. The Thundermax is closer to $1100 installedbut don't need dyno tuning. But seems to be the wayto go. Anyone with an 07 get the Thundermax?

 

The Thundermax ECM with autotune costs $749.00 at cyclespot, why in the world would you pay $1100.00 for it?
install it yourself, it's not brain surgery...

 

Installing the PCIII will take 15 minutes, the hardest part is taking off the fuse bracket...and you can call them (PowerCommander)and tell them what you are running and they will send you a map that is compatible...I got the PCIII for $270 shipped and the HD Dealer will dyno it for i think $180 if that is what you want. Although, I didn't have to have mine Dyno'ed since they had a map that would work with mine.

 

I had both.
I switched to the Thundermax.
PCIII is good,but the tmax exceeds expectations.
