ported throttle body

[Andy70]

I treated my e90 to a terraclean last week which I believe really made a difference and today I had the throttle body ported from 76mm to 80mm, I also think that made a tiny difference too along with my uprated air filter I put on too, all of a sudden the car feels perkier and a bit more throatier, its never going to break any records, but it seems a better drive than when I got it. I actually went to the porting guy as he removed it and done it while I waited, fantastic job, it was really interesting to watch. Cheers Gavin (if you come on here)
