With all this money we are spending on mods, we should first make sure our car is preforming is best right? Besides maintance how do we "tune" our Max? How do we know if everything is running its best?

 

Tuning is not really necessary until you introduce forced induction. 99% of the bolt ons available for the maxima can be handled by the original ecu fuel/timing maps. You might be able to squeeze a few more hp using a a/f altering device but it would take alot of fiddling to get it.
