many turbo duders on here so hopefully you can help, my car has the turbo and all bits on and its running, its forged and based on a bb tuning install with a bb low boost chip, sounds a bit lumpy and needs fine tuning, i have investigated the set up to sort it out diy, no mechanic but getting there, i am thinking of getting the r21 turbo injectors cleaned and then get a afr gauge and hook it up to the manifold, hopefully then i can use the fuel pressure regulator to fine tune the fueling to make sure i am not running lean, this with the injector clean will hopefully sort that out, i have no idea how to set up the boost side of it, any help much appreciated, i am thinking of manual controller as i can diy it, are electronic ones better? I am happy with 220 bhp so i only need to fine tune it from where it is, any help much appreciated as i havent a clue, thanks lads
