anything that will actually gain you hp will also require a $600 tuner. Plain and simple, there are no "cheap mods" that will gain you enough hp that you will actually feel. Even a throttle-body spacer will need a good tune to utilize it properly. Just enjoy what you have. I sure am! If you wanted a racecar, shoulda gotten an R34. At least YOU guys can get those.

 

Hi
Thanks. Yes I think I will do a tuneup once fit the exhaust and the headers. Will let u know guys

 

He's talking about tuning the ECU to maximize the effects of your mods. This is done by a company called UpRev and it's called the Osiris tune. A regular tune up will not affect your performance much. I also highly encourage you to read through the "sticky" threads at the top of the G35 Coupe sub forum to answer most of the questions you will have.

 

Hi
Thanks so much
