Ok, looking to see if a custom tune will benefit over the Cobb OTS tune I have at present with the mods I have below. I made 272 whp and 260 tq on my last dyno on a dyno dynamics machine. How much more do you think a custom tune will net get me above what I have at present?

2006 Revup

Nismo R Tune Headers
JIC Y-pipe
Motordyne Test pipes
Nismo Exhaust

UOR lightened Crank Pully
Apexi Drop in filter
JWT Clutch & lightened flywheel (in before tune)
3.9 FD gears

Just trying to decide if the custom tune is going to net much more power vs cost etc. All help both negative and positive appreciated.

 

A custom tune will typically get you a little more. If you are going to pay for a custom tune though I would highly recommend uprev. I have had cobb in the past, and though their customer service is good the unit is now unsupported by them and it fried my ecu when it crashed during a reflash. with uprev, if it crashed you just unplug ecu and reflash again and it picks up where it left off. seems cobb didn't get that far with development before they gave up on it. Also uprev allows a few more options for fine tuning that cobb also never got around to doing.

 

+ Cobb has been out of the 350z tuning game for a couple years now, Uprev is definitely the way to go.

 

Get rid of the cobb and get uprev and get a custom tune. You have a decent set of mods.

 

Uprev is what I used. My car was tuned through data logs and I made 267whp with my DE with full exhaust, intake. So I feel like you could be even higher considering you have a RevUp

 

That would be my hope since I am making around 270 now on a Cobb ots tune I would want to get into the 280s at least.

 

you probably won't get too much more though as thats already pretty high. I'd switch to uprev(and I did) just for the peace of mind and reliability. Also there are more adjustments you can make which may help you in the future if you do more upgrades or FI.

 

If anybody knows what values should I be data logging to see how outta tune the car might be. I am definitely not taking this car into FI as we already have an EVO and the challenges of FT in that.
