Why? Are you talking about vq35de's specifically?

 

Did you get retuned yet?

 

I'm getting the re-tune tomorrow. Will post results.

 

Did you get retuned yet?

 

So yesterday I went back to the dyno for a retune using Dsskyline's S1 cam/momentum header tune. And we threw on a revup airbox with k&n filter. They sent me the wrong dyno chart so I dont have a before and after, just the peak run for now.

Non-revup airbox baseline (same day): 205
Revup airbox: 210

Then, more importantly, they threw on the etune and optimized my car for it. Adding another 4hp. It did make gaines of around 10hp/wtq around 4-5k rpm.

The weather was nice today so I tested the new tune. Feels decent, definitely not slower after 3900rpm. This might be about the most I'm going to get from these mods.
