Chris, If you haven't adjusted your ALDA, adjusting it CCW about a turn and a half will do wonders. As your SD went higher, the ALDA naturally reduced fuel to minimize smoking. The springs and such have weakened in your injection pump, also reducing fuel delivery at any given point, but especially noticeable in the power area before boost comes in. Reducing fuel reduces power availability! Of course, way too much fuel will kill power too. But there is much room for improvement! Another problem is that the torque converter stall speed is set so low on the early turbodiesels that the boost cannot come in until the car is moving. On my car the boost is also locked out when the trans is in low gear. Both these problems were corrected by MB when they removed the low gear protection circuit in 81, and later loosened up the stall speed about 84 or 85. Many years ago we had the same problem with our 79 300SD. On the Pikes Peak road no less. We could go like hell as long as the boost was up. On the 12 % grade two cars had stopped in opposite directions, effectively blocking traffic, and we had to stop. Ended up backing down the hill to a flat spot about 1000 feet back. Kids were crying, wife was doing what wives do. No one else in the car really wanted to try it again. When the road was clear, we went, no problems! I have since learned to adjust the ALDA, and when my engine was out for overhaul, I had the local trans shop shim the torque converter for a little more stall speed. I also bypassed the trans protection circuit. Nobody beats me across the intersection when the light changes, if I don't want them to! Regards,
