I'm a bit out of the loop when it comes to these things. I usually rely on shops for the best answers. Didn't even know TFI was a brand.
I Strongly Suggest the TFI made and site supported by Dobecks...
Any Questions about their Piggy-back device Will Be answered By their Tech..
It is a simple fueler and easy to install....
After TFI is Installed and IF Later you modify down the road like I did when putting in a cam (SE255's) YOU Just make a simple adjustment with a small screw-driver on pot one.. NO MORE 150$ to HD ,,, the TFI does it Good...
Even after HD runs their 150$$ program it will
still be too lean
The TFI Made the BIG difference in my 09 FLHR stage one.. then adjusted Easily to work with my addition of SE 255 cams....
Noticed a BIG "seat of the pants feeling" using the TFI.
Many of Us on HDT have one installed and Swear by this nifty product...:small3d026:
Many other products out there, Most cost more$$ ,,,, but I prefer the TFI, So easy and simple to install and adjust..
As a member of HDT You can get a discount and IF you are military or first responder(or X) a BIGGER discount available.
The TFI unit runs about 259$ area,,,
And by Mentioning
Before you order with Dobecks Your HDT membership, they will give you your discount.... You can't beat that...
