I know that the HRVP44 is supposed to give good bottom end, and I know the Smarty gives great low end, so what would happen if I install a HRVP44? Would I have to turn down the Smarty so as not to break anything?

I have heard the HRVP44 is suposed to be more durable and would like to try one when the time comes, but really, I think I would want more mid and top end fuel.

Any way, does anyone have one who can coment?

Also, I would run only the smarty, no wire tap. Truck is an Auto.

Thanks Bob

 

The SHOVP44 seems to give more performance on the upper range, so I think with what I've hearing about the Smarty that they would work very well together!

 

If you need to replace your vp-44 and want more power, then by all means get the hot rod or super high output model for the extra cost of what a wire tap box would have cost you. If your vp is in good running order look at a set of injectors to go with that smarty. JMO.
