What performance mods are needed before a tune for a VQ35HR

[SonicT]

I have a 2007 350z HR,

I am planning to go get the car tune

I wanted to know what performance mods need before

i currently have a forced induction system, K&N gas air intakes and filter + oil filter, I have serviced the car and placed new spark plugs (Denson Iridium)

And finally I have a full cobra exhaust system

You can get the car mapped with just an intake, for optimal performance though, I'd go for a set of high flow cats or decats. 

 

As these are NA you won't see any crazy power gains but drivability and throttle response should be better. 

 

We'd recommend going to Horsham Developments for any mapping, Jez is your go to man.
