Richard, already, you are setting yourself above most with whom I do business. The People have been conditioned to work, live, and love alone and fail to find the strength we can only have when we work together.
Now, I want to say one thing about the EGR valve. What I recall telling you is that we "were looking at that sub-system" and evaluating the possibility of modifications. Now, that's NOT to say that you did a bad thing. Quite the reverse, in fact! I am thrilled you took the initiative in this matter.
What I would like is another post added to this thread that details EXACTLY what you did to the EGR, and the changes you noticed in operation as a result.
Now, you ALL must remember that to be accurate about the results of your modifications, they should be done in increments. One change at a time, monitor and record the results, THEN, and ONLY then, go to the next mod and follow the same procedure.
It's a finer point of developing consistent results, and will be unique to your vehicle. But it will apply to ALL vehicles that share your profile, so SHARE AWAY!!!!
God bless you, my new friend!
And thanks for becoming a part of the Gadgetman family.
