cam and chip

[TimXR6]

good morning all

Ive been recently looking into getting an HP4 cam and chip kit from Chiptorque

http://www.chiptorque.com.au/Ford/EF4.html

As you can see though the fitted price of the kit is $1750 for a gain of 15-20rwkw.

I am just wondering if better gains can be had by choosing a different cam and having them make up a chip for it. I have asked them about the specs of the crow cam they use but im still waiting for a reply.

It seems that people are getting gains of 20 rwkw without chips. Yes i understand chips are used for more than just power gains.

so, Would i be better choosing a brand other than crow and getting a custom tune to suit? or is their package the ducks nuts that shouldnt be changed?

cheers
Tim
