Hi guys,

My silver 2003 350Z tuned with intake / manifold / y pipe / muffler. I can get about 260RWHP and 33kgm.



Disappoint me when I installed cobbtuning ecu tool(stage 2 map). cause, only 250RWHP. So, I using Voloperformance's ecu tool kit. But, A/F ratio is not good. I want to get more power. (without supercharger, turbochanger and high cam) Do you have any ideas for my 350z?

Regards,
KIM

 

Test pipes/ headers would help. Better EMS, like a Haltech would help. Also, a traditional dyno tune by a good tuner would be beneficial. Regearing your diff to a 3.9 or 4.08 would help acceleration.

A better radiator, oil cooler, heatshielding your fuel lines and intake would indirectly help by minimizing heatsoak.

 

high flow cats or test pipes will help a little.
Not much else until you want to get FI.

 

+1. Very good response. I could barely understand what he said lol

 

Yeah, I'm sure his English is better than my Korean. I need to learn another language~ :-)

 

Does your car have the JDM ECU? We may have support for it. If not we could work on patching your ROM file so that we can support it.

 

Thanks for so many replys. First of all, my 350z already tuned these parts.

1) Greddy intake kit
2) Exhaust manifold
3) High-flow front pipe. (No Cat!)
4) High-flow Y-Pipe
5) Custom made center pipe.
6) NISMO Muffler

I think, Cobb AccessPort is crab. How many power do I get if I'll change ecu tool?

 

All a good tune will do is allow you to achieve the power potential that your car has. With the eTune service we provide, you'll get the most power possible without having to actually dyno tune your car, our have to buy an expensive piggyback or stand alone.

We do not currently have a Pro Tuner for South Korea, but we'd be interested in working with a shop there to offer our services so that you'd be able to get a full dyno tune on your car.
