If you would get a TFI, You could do Without all that $$ expense of the HD downloads..
The TFI is a Piggy-Back to the HD fuel system and it Adjusts accordingly to the "Need" that YOU program set it...
Using a screwdriver, set up the 4 pots with the Suggested Settings from Dobecks...
The TFI unit will allow you to Change ""Adjust Fuel Needed"" for the Modifications anytime.. Never a need for HD down loads.
Setting up the TFI/Gen3 is simple and easy to install.. The unit stays on the bike so any Later Modification of "add-ons" only require a simple adjustment. Saving you the need to do another HD download...
I use the TFI on My 09 FLHR.... I installed a Full stage one, along with TFI..... Right off, I noticed it Ran a lot Cooler... With the proper TFI Fuel mix along with the stage one parts. it gave me ""Power Felt in The Seat Of My Pants""....
THEN recently, I added SE255 cams... I was surprised that the TFI fuel mix needed to be
lowered , only a simple screwdriver adjustment Down one mark on pot 1 did the trick.... Smooth running again with proper fuel mix and NO HD map needed.(.)
The bonus is: I got a few More miles per gal.... from 40/42 to 42/46 under Same conditions, roads and riding style..
