I have a 1991 Audi quattro with an AHU, a 12mm LT AGK pump, K14 turbo, now with new nozzles. It's been on the road as my DD for a year and a half.I've been driving the car for over a year with a set of new T4 injectors out of the box. It turns out, they were not .216's as promised but a smaller nozzle with a higher breaking pressure. It caused the engine to run in a very narrow power band and very noisy at all rpms. I changed the pump timing many times looking for the sweet spot.New Years Day I installed a set of new Titan nozzles I've waited 8 months for and it runs beautifully now.Pump as it arrived from Berlin via Czech Republic.I sent the pump initially to Giles to calibrate for my application. The pump was already factory rebuilt so all he had to do was adjust it (whatever it is he does). After I installed the pump but before I started it; I noticed that the yellow sealing paint on every screw was undisturbed. I examined and re-examined close-up pictures I took when I first bought it and they were all exactly the same. So I inferred that he never opened the pump and so it must have been OK(?) He changed the mount bracket after I asked him not to, as I have several. As it turns out then, I had no real reason to send it to him. The pump starts and runs well; but still has clatter under part load. I am looking to adjust the axis governor and would like some input on this. Not so much how to adjust it but whether or not this might help. This pump was originally set up for a lower rpm engine and I think the axis shaft should be turned out a half turn (CCW)? I've had no luck finding any pictures of the inside of an LT pump if anyone can point me in that direction as I want to understand how the low smoke governor works as well. I have rebuilt and repaired several IDI VE pumps, and I'm very familiar with them.I've had my project/thread posted on 2 other sites for a few years now. A lot of fluff, K&N filter debates, and dyno queens. I find most who post on this site are more nuts and bolts, grease under the fingernails and most importantly share with me a fierce love for the mTDI. The last reason is what really sets vwdiesel.net apart from any other site. Kudos guys. Thanks in advance.Rich B.
