Just fitted NGK BKR7Es ( think thats right ) onto my REVO stage 1 APY S3, gapped correctly to 0.7. I now have no boost/feeling of having a turbo. The car now drives correctly until you put your foot down and nothing happens, found this out whilst trying to overtake earlier. There is no boost whatsoever, it still reaches topend speeds but only after about a year, like driving a mk4 golf gti 2ltr jobbie.
I have gone over every connection around the boost system, charge pipe, red turbo pipe DV connections and everything is spot on, the only logical thing is the plugs, does anyone know why? I'm going to put the old ones back in tomorrow just to try and clear it up but I want to find out what happened.
The plugs were recommended by a thread on here so I don't want others to have the same results as me
