i'm thinking about getting the jetchip ecu upgrade...
the website (jetchip.com) has horsepower increase at 15+ for the maxima.... this is not the air fuel console, but actually modifying the ecu. Anybody have this, or hear of anybody having success with this? I already have Ypipe, CAI and cat back exhaust. Looking for more horsies... giddyup

 

save your money and if you are determined on getting an ecu upgrade, get JWT which can be done to your specs. Remember, once you upgrade the ecu, you will be limited on additional power add-ons which may conflict with the chip.

 

the jet chip does nothing for our car.. it was dynoed and there was no gains..
