Turbo overboosting

Hi Chaps, I know you are all probably bored of my overboosting problem by now [:(] but please stick with me, I am trying to get it sorted. I bought an accuboost from Andrew to replace the brass restricting valve that was attached to the wastegate pipe, I have also fitted a standard shut off valve in place of the non recirculating dump valve. I have released the accuboost pretty much all the way out which has reduced the boost a lot, despite this I am still hitting the stop on the gauge when I put my foot down all the way. I tried to check the chips (KLR and DME) but the mass of wires put me off ( alarm/immobilser box installed in footwell with yet more wires all cable tied together ) Could this problem be down to the chips alone??? I am beginning to think it might be the dials (the originals have been replaced with white dials) and the temp gauge is faulty as the fan cuts in when the needle is just above the first white line. How easy is it to fit an external boost gauge?? Cheers for your patience [:D]
