2 weeks ago I went to a local Nissan Tuning shop called Churches Automotive. They performed a dyno tune on my car and optimized my ecu to work with all of my modifications. They also removed the speed limited, removed the throttle body limitation (it will now open 100%), and put a total of 5 tuning maps on my original ECU.

It is very cool, I can switch to different tuning maps using my cruise control switches. I can switch from performance, original, economy (better fuel economy), valet (car will not go over 4000rpm or 40mph), the 5th map I left blank.

My baseline dyno: 258.9 rwhp, 237.1 lbft torque


My dyon after the tuning: 273.5 rwhp, 258.8 lbft torque


The dyno used is known to read pretty high, so I truly do not believe that my car has that much power. I will go to another dyno that is known to be more accurate and compare the power differences. Regardless of the numbers, the car runs much better now! It feels much quicker and responsive throughout the entire power band!

I also got an Osiris Uprev kit. I will post more info on this when I have time to take pictures and video. It is a OBDII cable to usb cable that plugs into your computer, and with special software, records and monitors your car as you drive. It also monitors for any error and diagnostic codes, and allows for some adjustment to ecu and bcm functions!
