Stillen supercharger long term reports

zmanelite, you should not be driving the car!
let it get looked at by an experienced tuner, looks like there is something wrong with either your map or fuel supply.
If it is throwing lean codes, it is definitely way to lean for forced induction

as for the P0106 MAP range problem, tell your tuner to disable the DTC in your map file (this is normal, the MAP sensor is not supposed to see positive pressure, as it is an N/A vehicle after all)

I would definitely recommend adding an AFR gauge, for any kind of aftermarket boost it is essential to always know AFRs are good, especially if you floor it

As for downpipe/cat upgrades, i read a lot about that and most people will tell you that downpipes/cats or TPs will decrease boost on the stock pulleys/impellers.
I have just installed this kit, i am running stock headers, berk HFCs, Motordyne XYZ Pipe and Tanabe Exhaust, so pretty much everything except for headers.
I am seeing 8psi on the dyno and 9psi on the road, so i consider this to be a myth.

Hi niko86, Im curious. Stillen told me the headers would cause a boost loss and lean AFR whereas HFCs would not take the elevated temps.
I still have my Berk HFCs in the box (purchased them recently). I loved the idea of better flow, an extra O2 wideband bung (coz i wanna get an AFR gauge too) and spiced up exhaust note. But now I'm tempted to return them to Z1 Motorsports because of Stillen's advise. I was wondering how your Berks affect your kit. If it's really the temerature stress I guess you wont be able to tell yet since your kit is still faily new. Well, good luck with it i hope they last you long.
