(01-16-2012, 03:20 PM)toyfreak I only gave up so quickly because I was trying to get my truck running good so I could go 4wheeling. I have been building it for the last two years, and the IP was the only thing holding me back. I will continue to adjust it, just don't always have time to do it. After I make a socket for the TC, I will start tinkering with it again.

The ALDA is adjusted 1/2 turn from all the way out. It gives a nice puff of grey smoke, sometimes almost black depending on how I take off. I am sure I will have to adjust it later once I start to get more power out of it. I'm not into the roll coal on everyone behind me.

Throttle linkage is good for how it is set now, but if I adjust the Horizontal Throttle stop, I will have to readjust it.

It is not easy, but definitely not the most difficult thing I have done.

Once again, thanks for sharing your knowledge on this subject and helping me figure out my IP.

Sounds like you need to also do more of what you did to get the idle back down some, I assume that you backed off the Bump Stop, if so, I would back it off another 1/4 to 1/2 turn and set the idle governor speed.

The ALDA doesn’t have enough adjustment in it to make it a real performance change, lifting the ALDA with some shims will put it in the range you want and will still let you turn it down if you want.

It is not so much that you want to increase the max delivery as the end of injection will be late and the turbo can only handle so much efficiently. The power increase comes from delaying the reduction in fuel as the RPMs increase, that is where the Torque Control comes in.

Pay no attention to how someone else adjusted their IP, No two are the same, for example, your bump stop may not have been right from the start. Keep working with the Torque Control until you have CONTINIOUS BLACK smoke under at full power as the engine revs through the power band, then back off the Rack Limiter to eliminate the smoke, that will give you the power you are looking for.

Turning up the Max Speed will extend the power band, but again watch the EGT, I put a longer screw in mine, the stock ones are only good for a couple of turns.

Keep an eye on the EGTs and the boost close to 15 PSI.

The First IP I did, I had the back plate off about 15 times, then the Light bulb came on, the second was only 3 times, now I can tweak a governor in one shot (for the most part). The Bosch class was a bust for the most part, they were definitely not into performance adjustments!

I think you can see why I do not recommend anyone playing with the governor, it so easy to get into trouble, and expensive to get out.
