Hi, have searched and this seems to have been covered many times. The general concensus seems to be don't get one. I have one of these already fitted to my car. The previous owner said it used to throw up a warning light until he had it re-setup and now it's ok (which it is, no warning lights). The dump noise on mine isn't loud at all so wondering if it's been setup to recirc 95% of the air, enough to keep the ECU happy. Is this possible with the Split-R?
Not sure whether to just replace it at some point anyway. Gonna be getting full exhaust and FMIC, then stage 2 remap, so maybe worth changing then? What are peoples opinions??
