I am going to get a tuner and pulleys, but i am not sure of the order in which to get them. If i get the tuner first, will new pulleys require a different tune?

 

No they should not require a different tune.

 

I spoke to Doug specifically on that, and no, he said you can't really tune for pulleys.

 

ya, all the pulleys do is run the accessoires slower, allowing the engine to use less power to turn them. its not actually giving power, but freeing it up.

 

where can you get this stuff at?

 

Just ordered the 25% underdrive pulley for the 4.0L OHV from UnderDog Performance.
This should work well with the other mods I have done.
Hope to notice a little MPG increase too !!
Haven't read any about others doing the installation on an OHV. Once I do the installation; I will do a short write up.

OR 4x4

 

^^Awesome..cant wait!!

 

the ASP pulleys we sell will work with the OHV, we sell the pulleys and tuners. i believe graniteguy sells the same pulleys.
