Word. Sorry for the distraction...........

Anyone else with some Stillen goodness?

Mine should be on by the end of next week and I will have some data to enter.

:iagree: same here. I have bad things about Stillen Service, Vortex rules, they fixed what Stillen couldn't. Should be installing soon, then I'll have some data for ya!

:happydance:

Can you be more specific about how Stillen failed for you?

biting my tongue :roflpuke2:

Dude were do I start?
1. Customer service doesn't call back.
2. Customer service doesn't no anything about the kits they sell.
3. Customer service will refer you to a tech for everything.
4. Tech doesn't fallow through on your orders, so no call back or shipment.
5. It took a week just to find out the belt sizes.
6. I filed a Better Business Complaint and got a call from Service Manager to work out the complaint. I sent detailed pictures of what I need, didn't get a call back, 4 days later I call. Still no action, need tech to figure it out.
7. 2 weeks working with Service Manager, still no drive pulley.

I still need the F__ing pulley and still F__ing don't have it. Vortex sent what they thought it was but its not right size. All I need is the Stock Pulley sounds easy but Stillen can't do it!!!

Anyone have a stock drive pulley on the impeller side of the SC that takes the belt that runs the Alt, PS, etc. of the SC. I'll give you a cheese burger for it!!! This is what has been holding me up on my install.

Attached are the pictures i sent; what I thought was the pulley is to big. The Kit is good after swapping out plastic BOV and Idler pulley.

That is all without a doubt unacceptable. I can tell you that customer service has been responsive for me, but I have always just gone back to the salesman who sold me the kit. So that is the good. The bad is I am also having a minor tune issue. Seems to be a lesser version of what Shamu reported.

Under hard acceleration, not necessarily WOT, but still pushing it she runs fine. With casual driving she seems to both hesitate and surge between 2800rpm and 4000. Above and below those numbers she runs fine.

One of their techs - Sam Camarillo - has a Cipher run from me and is working on it, but after 4 days when I got impatient he stated, "Still looking at data. Will have to dig deeper as I haven’t seen this before."

So the good thing is they are working on it.
I will update.

Gotta wonder, does any one have an FI kit on their Z (from any vendor) that installed and ran flawlessly from Day1?

GTM :tup:

I'm having this exact same issue. Had my tuner data log it while i was driving the car...says the MAF's voltage is fluctuating a whole voltage up and down like it doesn't know what to do. Mine is occurring around 2900-3200rpm (normal cruising rpm) But when i'm on the accelerator the symptom goes away. Prior to upgrading my bypass valve, the issue occurred at a higher rpm range 3500-4000rpm. The theory is that it is air turbulence on the MAF's and/or poorly designed reciruclation tube where it connects back into the main tube going into the blower. The recirculation tube right now basically T-bones into the main tube when ideally it should curve into it facing the blower.

But as of now, i have no solution. The shop i take my car to wants to extend the pipes before the MAF's to see if that would help. So if you find a solution, please let me know.

Im happy with mine. 410whp and 305wtq. Everything else is stock except a stage 2 exedy clutch. I smoke vets, M3's, etc... I have about 7,000 miles on it so far.

I agree. I test drove two 2010 Z06's before I bought my Z. When I first drove it after having the Stillen SC installed the first word to describe the power that came to mind was "brutal."
I have no complaints about the power this kit produces. My only issue now relates to drivability.

you can build a air box that should fix the problem. I took some thin aluminum from lowes and bend it around the front crash bar under the filters and up around the back of it. I did this and do not have any problems at all. this will prevent direct air from entering the filters and causing the MAF's from getting a bad reading.

kellyefields,
What led you to make this airbox? Were you having the same drivability problems as we are describing here?

Can you provide photos of the solution you came up with?
Thanks.

do you have a pic?

also, i know there's a shroud that comes with the kit already that blocks air flow. But i'm assuming yours is larger and placed differently? And as irondoc stated, did you also experience these symptoms?
