Can you use a Vance and Hines fuel pak be used with cams, or a big bore and head work???

 

They only have settings for their pipes, high flow air filter, stock and stage1 downloads.

 

You need to look for a Fuel management system that is SPECIFICALLY DESIGNED for that type of build......

SERT, PC (within reason), Thundermax (Replacement ECM, or VFI ECM (S&S replacemant ECM) are a few of your choices.... There are probably 1 or 2 more....

The cams and headwork warrent a lot more than just modifying the fueling aspect of the motor...

Spark curve, MAP table, Trimming the fuel in each cylinder.....

 

Just talked to V&H & they are workoing on settings for these mods.
