I have a 2008 G35X sedan. I've been looking at different ways to boost output and/or fuel performance, such as performance chips. Do you have any suggestions or opinions about their effectiveness and whether they're worth trying out?

Are there other ways to improve performance and/or gas mileage (OK, other than using premium gas and trying not to floor it out of stops ... I already do that).

Thanks.

techno square does a great job with their tuning/chip for performance. for better mileage, go cheap and get K&N air filters.
most good performance tunes will not get you better mileage.

Air filters will really get your better MPG?

 

Good question. I put in the drop in K&N's 6 months ago and its hard to tell if there is a change in mileage because so much is based on how you drive the car from day to day. If there is improvement it is very slight. I can definitely feel a performance improvement though.

 

so has anyone chipped their car?? so far i see opnions and comments but has anyone actually done it?

i had a 5spd passat years ago that was chipped and it was like twice as fast as my friends non chipped one. i'm wondering if it will be the same with my g35?

 

I have the UpRev Osiris tune, but it's not really a chip persay.. it's actually a full custom ECU tune like Technosquare. You'll need to go to an authorized UpRev dealer to get your car tuned.

 

^^+1 was going to say the excat same thing. It depends how much you are willing to spend on performance.

To answer your next question... Yes there is a noticable difference. On paper and driving, this also depends on the mods you have now and are planning on doing before your tune. GL friend.
