NISformance Mail in Re-Flash

This service allows you to send in your vehicle's ECU for our base tune. Our base tune offers gains throughout the powerband while retaining a safe margin. This service is intended to be used on naturally aspirated vehicles with light to medium modifications such as intake and exhaust upgrades.

Advanced features for the 02'-03' Maxima. These features introduce a major advancement for the 02'-03' Maxima platform. These features allow us to offer multiple maps, launch control, flat foot shifting and shift light. Prior to this, only UpRev supported cars had this ability.

We will be offering these features as an optional upgrade with our mail in re-flash service and as a stand alone service for those who are tuned by a different tuner. If tuned by a different tuner, we can add these features without affecting your current tune. Please send us a message or email for more info.

5 of 5 2004 Maxima August 29, 2023
Reviewer: Michael from Saskatoon, SK Canada  
I'm very happy with the tune so far. The car feels different and I have to say I was very surprised. It's revs higher, accelerate faster well still getting the same gas mileage and even better. The customer service is also very helpful and friendly, they would email me about any issues. I even got told that UpRev ARC License is not compatible with my model of ECU, so they ended sending me a refund.
Overall I'm happy with how this turned out.

Reviewer: dustin brunton from Newark, OH United States  
I haven't installed it yet, as I am still in recovery from surgery. I actually wanted to know what was performed, and how the car will drive differently. Did you take off the speed limiter? How many horsies did I gain? Ball park...
