If you do not tap the wire, you are looking at only 60-65hp gains.
There are several options.
Smarty
Edge EZ
Van Aakan
I would probably list them in that order, personal opinion.
If I were you, I would get the Smarty. That way, when the bug bites and you want more HP, you can stack other "chips" on top of it.
Im looking for a new performance chip and there are so many out that im not sure which one to get. Im looking for one that'll add a reasonable amount of power, without tapping the wires on the vp44 pump. any suggestions? comments are welcome too.
