Looking at chipping my AT '03 G35.

Does any one have any suggestions, thoughts or recommendations? What kind of power increases can this potentially give?

 

No chips for the G do any good. All of the ones advertised are crap and a complete rip off. You need to get your car tuned, look into the Osiris tune from UpRev. There's a lot of info on it here on the forum.

 

Complete your breather mods and then get an Osiris tune! They tie your G down making a few runs showing you where you're at before making adjustments. Then they tune her and show you exactly what your gains are...that is the "Best Bang for your Buck!" SLICK ended up with +25 whp and 19 lbs torque, that's an increase you can feel the minute you turn the key. Some members claim better results, I was happy with what I got!

+1 an Uprev reflash is what you need. Do you have a coupe or sedan?

 

It's the '03 automatic transmission, coupe


Wow, glad I joined this forum. By the sounds of it, it saves a ton of wasted research and trial and error. Thanks for all your guys tips

Ok thats good. Some of the early sedans still have the old style ECU and aren't tuneable, but all the coupes are good to go

 

can you not modify OBD 2 ports?

 

Not about the OBD port... it's the ECU... lacks a lot of features the newer ones have which give it the ability to communicate with the tuners.
