Hmmm. I don't remember reading that rating/specification before. My auto failed with the engine stock. IMHO, I think "...
might hold 300hp. " would be a better way to put it.
I'd 2nd the opinion for the Smarty. I have owned an Edge Comp for several years now and really liked it. Now that I have the Smarty I don't turn the Comp on anymore. Sure, Smarty gives you less total power than a Comp or Edge Juice, but it is a LOT more fund to drive than with just the Comp. After the Smarty, build up your trans and then add a nice set of injectors. This is what I run everyday and it is reliable and plenty of power.
