And with an optional drivetrain warranty available, with $8,000 of coverage, those looking for that extra bit of security in their back pocket can have it.

My recently installed Stillen CARB legal kit only made 349 WHP and it was installed by well known shop. Stillen tune isn't much better at low end than my NA Nismo tune. My NA nismo actually made more torque at low end.

It has a nice mid range to top end pop. They are definitely working with my installer to make it better.

It's a centrifugal supercharger, of course low end boost is lacking. That's by design.

Yes however even centrifical blowers make some boost down low.and i still think there is more that can be done with VVEl mapping with Stillen kit.

I still think Stillen is the way to go as non carb legal kits are a hassle when smog time comes. I do appreciate the hard work Stillen put into getting CARB certification I just hope I can get carb legal hp numbers closer to what I have seen from other installs.. And truly if your not worried about carb why not just do proper twin turbo?

Having spent more time with their kit it does work well the tune just needs a wee bit of tweaking. I think I will have some real improvements soon with my carb legal tune.

You can not tune VVEl at all,If Uprev hasnt come out with it then Stillen cant do anything about it either.There using uprev software, I do wish there was a way to tune VVEL,a tweak to your tune will give you a little better results. However some of the other installs you are talking about with better number's have the smaller pulley.Like the dyno chart posted in your thread, thats with the 9 pound pulley from Stillen.

I dont think you will get the low end you are searching for from the Centrifical blower,Unless you up the boost some with a re tune.Every dyno I have seen from the stock pulley doesnt even break 300 ft lbs of torque. I hope everything works out for you though man I really do.
