Stillen & limp mode?
 

Anyone running stillen s/c have any issues with randomly going into limp mode? It's happened to me now a few times and wondering if anyone with the kit has had same issue and/or knows what the cause/fix is? I'm running their out of the box tune...

Does it happen when you are coasting?

I had the same issue, I narrowed mine down to the MAF extension. I never contacted Stiller or checked with a multimeter but it was definitely the cable. I moved at another direction and I'd go limp and throw a code. Turned her off then back on and she would be fine. It's been a year so I don't remember the code.

Same here. Had the issue a few weeks ago. Rerouted the throttle body harness extension for a short term fix, and ordered a replacement for a long term fix. After swapping out that extension, haven't seen the issue come back.

Mine had happened both whIle coasting and while under throttle. So a new MAF should do the trick?

I'd try a new cable before replacing the sensor itself? You'll need to clear the codes too

Double check the extension cables, doubt it's the MAF
