Stillen G3 intake and exhaust no low end power
 

2010 370z sports manual. Running a basic Stillen G3 intake and exhaust setup for the last 2 summers and so far I've enjoyed the sound, and the little bit of extra power. The one thing I hate is that complete lack of Low end power. If I'm anywhere between 1500 and 2000rpm and I drop the hammer, all I get is a loud growl, and the acceleration power of a golf cart. If I keep the gas pinned, it takes about 1.5 seconds until she goes flying. What is up with that? I only have about 20,000km on this setup. Is it a bad install? Should I get the air filter cones cleaned? They're K&N cones right? Any thoughts or is this completely normal with this setup.

Sounds about normal. Look up on here throttle lag. From what I have read it can be corrected with a tune.

The lag is normal, and could only be fixed with a tune via UpRev or using a Sprint Booster module.

What other mods do you have?

Most opt to also upgrade to a less restrictive aftermarket exhaust.

And a tuned.

The bottom end loss? is perfectly normal only to gain it at the top end or higher rmp.

Thats the trade off for going BIGGER! ;)

No other mods. I guess a tune is in order. I read about it. Thanks for the input fellas!!

Tune will take care of that for sure, I have a auto and if I jam it in the RPM range the car rips off! :)

Fixed :tiphat:

Which did you go with? Ecutek or Uprev? Or something different?

I got an Ecutek tune back in 2013 when I was completely stock except for R2C intakes. Throttle response was dramatically improved :tup: :driving:
