NISformance Mail in Re-Flash

This service allows you to send in your vehicle's ECU for our base tune.
Our base tune offers solid 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.

This service is not available for forced induction setups. You must ship us your ECU, We do not provide an ECU. This is a re-flash service.

03' G35 Sedan tuning: We are able to tune the stock ECU in the 03' G35 sedan with the early style ECU. Only a single map is available at this time. Multiple maps are NOT available.

Note: Adding the optional ARC license(04'+) allows for improved ignition timing strategy. This results in increased power gains but also a much improved "pops and crackles" map.

5 of 5 05 G35 ECU Re-Flash May 9, 2023
Reviewer: Lance from California  
Car runs great after the tune, nothing too dramatic being NA and a handful of mods, but better than before and I feel that everything is working together now. There was a misunderstanding on my part and they went above and beyond to help me out with it! Fast turn around and a good price. I will definitely use them in the future!

5 of 5 370z mail in flash tune March 29, 2023
Reviewer: jaden schultz from michigan  
amazing , out of the few places i looked into for tuning my car , nisformance had the quickest shipping plan so i chose them. they use uprev, which is a commonly used software amongst the z and g community , expect i think they do it better than the other options. their response time and explaining of things was perfect , really eased my mind on anything i had questions about. their price was the best also, i.believe they were the cheapest option, long story short , i’d highly recommend nisformance , they’ll answer any question you have and get everything done in a timely manner. 10/10.

5 of 5 Disable Nats June 15, 2022
Reviewer: Danny  
My Nissan Pathfinder haven’t run in over three months, I was about to give up on it and have it towed to pullapart but I stumbled across NisFormance website (Website need to be more visible across more platforms) and they were able to do what nobody else seems to be able to do and that is to disable the Nats. Thanks
