EFI tuning

OK, I have read about PWR COM, SERT, Fuel PAK and some others. I get the ability for some auto tuning in the real expensive modules. I understand that with a fuel pak I have to manual make adjustments. Here's the deal. I put on V&H Big Shot Longs because I like the way they look and sound. I am not trying to go racing or be the fastest guy around. I just want to have the bike run smoothly. With this in mind.... Can I get away with the $245.00 to buy and use a Fuel Pak?

Here is what I would recommend. Have this on my '03 UC. Very user friendly, "plug and play":

Re: EFI tuning

I would also sidestep the fuel pack and go with the TFI. Much easier to use and adjust.

Re: EFI tuning

Does the TFI mount the same way at the fuel pack? Also what changes will it make to your fuel mixture?

No

the TFI goes directly to the injectors after the ECM, were as the Fuelpak plugs into the ECM

Re: EFI tuning

It will change the fuel added however you set it but it uses no mapping, it adjusts with small screws electrically.

Many topics on this in the self help forum...
