Hopefully they can figure it out without having to drive down to stillen like u and phimosis to get it fixed

Yeah! I feel you! Driving down there not knowing what kind of risks you're taking in damaging your engine is not a very good feeling at all. My butt kept on squeezing together whenever I felt the lag and hesitation lol.

It's weird how you're having issues and you're an 6mt also. Most of the people are 7at that is running into problems.

Stillen was much more active in this thread before kits started shipping..

Is Stillen and their dealers still selling kits? They should have a freeze right now on any new kits while these problems are worked out. I hope this is the case.

I'm pretty sure they're gonna come up with something very SOON.

have you gotten an independent dyno after the fix?

Not yet, my local tuners dyno is down and I'm waiting for him to fix it then I'll get it dyno

i am fortunate and unfortunate at the same time but my car is at Stillen. Fortunate they have it so they can work on it on-site...unfortunate because my car is 400miles away and havent seen the car in a while.

Hopefully with your g37 and phimosis 370z 6m down at stillen they will come up with a fix soon.

You don't check your pm much do you? Lol

The kits are on hold I due know that, which is BS because the kits can installed and the tuning can be sent later.

It does sound like Stillen is getting things handled correctly with the Uprev people involved. I like uprev but i have my complaints about it so when christmas comes, this guy is looking at Haltech or something else that gives me a lot more control of the ecu.

I think it will all be sorted out in due time. The lag, bog, black smoke and unburnt fuel
smell are no accident. It's from setting the mixture rich.... Mine was running at 11.1:1. Ignition retard is also involved in that bog/low torque output setup and sends unburnt fuel into the exhaust. When a car runs like that, it runs cool and without detonation. It's "safe", but is low on power and has poor throttle response. If you leaned it out to 12.5:1 and advanced the timing 5 degrees or so, the car would spring to life and be a lot closer to emissions targets, make more power, have better throttle repsponse and get better gas mileage. Independant tuners are tuning the car this way and having good results. Like RCZ, right? What that tells me is Stillen either has evidence that damage is occuring under high rpm + high boost conditions when mixture is leaned out and timing is advanced, or they just suspect it and are afraid to lean it out for fear that someones engine is going to blow up and they get blamed. That becomes a PR disaster. If someone 's supercharged Z blows up with a stillen kit, but a tune from someone else, they can easily deflect blame and say it was improper tuning and say that none of the cars that they have tuned have had problems.

Thanks for the update seems stillen is being very quiet about this problem and when I should expect a new tune. They told myself and my shop its safe to drive but I decided last week just to garage my car and not drive it till they figure this out. Is your car still down there at stillen?

I agree 100%

Looks like its supporting mods only for me this year :shakes head: Hopefully all is sorted out soon.
