is says it will work on any size enginge and give you 3-6mpgs, and upto 50hp

 

those are fake. Doesnt even say how it gives you the horsepower and its a wire connected to a switch. Looks like an 80$ light dimmer.

 

looks too good to be true, if that truley worked as well as it claims i believe this would be much more widley known since 6 mpgs is just unheard of let alone the hp boost from $80.....so i would have to say, just from its claims that it doesnt work at all or nearly as well as it says it does.

 

you could just buy a cam... theres no way to not feel a difference!

 

It's a resistor with a ****, worth zilch. Don't waste your time or money with that garbage.

 

same junk they sell on e-bay but for less money

 

did not know they made a cam for a 4.7l

 

yeah, they make a few.. 203's all the way up to like 260's i think. it'll deff wake 'er up!

 

explain a little please not to familiar with cams. What does 203's all the way up to like 260's mean?

 

it's the grind type, the higher the number, the more wild the cam. The 4.7L can handle a 206 cam without any modifications except for a tune, for 212 and higher, you need new heads, the works. The highest cam I know of for the 4.7 is a 224, although they make em for the hemi's up to 268. Putting in cams is not a cheap undertaking.
