I had my ED30 with a GIAC map (with flash loader) always set to pump, along with a Forge CAI and Forge DV, the car went great, no hassle at all. I then bought a second hand Blueflame downpipe and sports cat off of here, and fitted it along with a Blueflame system i had previously bought off of here. Now the car runs terrible, its holding back big time, engine management light came on, fault showing bank 1 catalyst below threshold. I was also told it could be down to fuel, so fitted Autotech HPFP internals along with Rs4 return valve. Which has made no difference at all. Could there be a problem with the cat? The system doesnt sound loud at all either, its holding back up the rev range. its crap to be honest
I just want my performance back
