Stillen SC and Invidia Gemini Exhaust ??
 

Now i have my car at Stillen and after a few tunes on the Dyno they can only get 386 HP out of the car and they are saying the problem could be the Invidia Gemini Exhaust

According to Stillen a Nismo with stock exhaust puts out around 416hp or so

So my question is , Anyone in So cal have a SC and Invidia exhaust ?
If so what numbers are you putting out ?

Car is a 2012 370z nismo 18k millage and put out 279 whp with Invidia and Takeda intakes

Im gonna go drop off the stock exhaust tomorrow and hopefully it can get close to 400's , kinda hard pill to swallow after droppin so much coin on the kit

I am not saying it is not true but I find it very hard to believe. Does the tuner do a lot of 370s?

^^^^ Have no idea but being the kit is form Stillen and they are the ones doing the job i was hoping for a easier no hassle install

Tomorrow they are going to try out the Stillen cat back and if they do not find the extra HP I will go from there

Maybe there's to much flow just like how they want the stock cat on for more HP and boost.

That's hard to believe any way you cut it, My car with Stillen Gen 3's and Exotic Speed cat back( True Dual 2.5) Stock cats made 298 WHP (UPREV) .
With the Stillen kit and "their Tune" car only made 342 WHP( Tune was CRAP) ? I went custom tune and got 412 WHP so I gained 114 WHP and you gained 107 so not that far off, Was your car dyno'd at their dyno for the 279 run? If not their dyno could be SUPER LOW!

Call Sebastian at SpecialtyZ if you decide on a custom tune. Hands down the best Z tuner in the area.

Yeah it was all done on there Dyno
In order to do a custom tune on the car does the Stillen kit have a piggyback ecu ?

Do you have any contact info on SpecialtyZ ?

Thanx!
ill see how stuff goes today before i give them a call

stillen tuning is garbage

just do a search on here dude. don't waste any more time at stillen.

There is no way even with a nismo that with the stillen SC kit and their canned tune will it put down 416whp. My car has the stillen SC plus 9lb pulley and headers test pipes and the cat back exhaust and with a custom tune from r\t tuning I'm making 440 at the wheel which is exactly 50 more at the wheel over the stillen canned tune so I call bull****. Also my car is not a nismo

And there is no way that their cat back exhaust is going to add 30 more at the wheel over your invida! Again I call bs!

You running 91 or 93 oct? ^^^^

As for the Stillen tune from what ive heard the new tune is not that bad

Maybe i was expecting more as the numbers i was told were different than what really expected
I was told 450 to 500 but im guessing that is at the crank now vs BHP

450 -500 WHP on a SC your motor will most likely pop Too much boost to make that number! I was at 11-12 PSI and 460ish WHP motor gave up.
Their kit BPH is 515, WHP tuned and custom tune and custom tune only will net you low 400's.
