I just bought a 2005 G35. It's all stock, and more than like will only get a cold air intake and a chip.

My question is this. How much would a dyno tune help, and is it worth doing. I have access to getting one done inexpensively, but don't want to waist a couple hundred bucks if it won't give me any added horse power.

 

Chip should hook your ride up..

 

get all your bolt-ons first then tune.

While you're at it, try out those electric superchargers. I hear they add hella horsepower.

 

........I see we have more than one Joker on DRIVER! I saw post here a few years ago that doing a tune on a totally stock G35 will allow you to pickup a few RWHP. Personally I'd wait until you've made all the modifications you intend to before doing a tune.
