just ordered k&n drop in filters, berk hfc's and getting an uprev dyno tune!

was hoping for about 310-320 whp

accurate guess or no? i saw that the stock ones usually dynoed at about 280whp

2013 g37s coupe 6 m/t

 

290-295 depending on the dyno and what the weather is like

 

The best thing to do is dyno the car first with out any mods, then add them and do the dyno. Then you will have an idea of what the increase in HP is. All dynos read differently and saying you have 310whp means nothing. Saying I was able to increase my whp by 15 is saying something. I can increase my whp just by going to a different shop for a dyno.

 

Gains will be minimal.

 

weird was reading on other forums that i should expect gains of about 30 whp w/ the cats, intakes and the uprev tune

 

40 whp seems like an awfully large gain for a NA engine with minor mods.

Share your dyno once you do the mods so we see how much you gained
