Has anyone retuned their NISMO?
 

Hey guys. I was wondering if anyone else has had a retune performed on their NISMO after a few minor mods. I have installed K&N drop in filters, Z1's post MAF tubes, and Berk HFC's. I am not sure if the factory tweeks to the NISMO ECU are sufficient, or if there is still a little performance left in the car after these mods. . Would I be throwing my money out the window?

I just recently had mine tuned on a dyno jet after installing my fast intentions CBE. Before that I had the nismo CAI and berk TPs. It was running VERY rich before the tune, so it benefitted me a lot. Do you have a CEL?

No CEL's here. I am debating between a dyno tune and Z1's mail in flash service.

I got mine tuned at RT Tuning after I installed 3G's, FI LTH's, their CBE and a few other tricks. Picked up a few extra ponys, gas mileage and smoothed out the gas pedal.

To be honest I would be happy with just getting the pedal map worked out. I have had a couple of cars with throttle by wire, but the Z's throttle engagement seems to be the most artificial.

Don't know about the mail in flash, but the dyno tune will allow the tuner to see exactly what your car is doing, and how to tweak it. My throttle response is definately smoother, I'm not running rich anymore, and I picked up some good power. My tuner also threw in a cypher cable so that I can data log. Should I choose to do more mods, he can tweak it again without the use of the dyno.

Dyno Tune!! No other way to go! Stillen CAI, FI Test Pipes, FI CBE.. then tuned it.. runs great. The guy said its running around 385-390HP now.

At the crank?

Has to be at the crank. Same bolt ons here ended with 300 to the wheels.

to be 390 at crank you need 330whp? pic of dyno sheet. we love seeing dyno sheets
