Thanks for the great info, Dave!

My SDL is running 0-60 in about high sevens early eights now(and I can prove it). That is better than I would have ever dreamed to achieve (with 3/4 tank of diesel and all my junk too).

Now when I get that custom-made Mosselmann intercooler..., That's when I'll tweak the internals of my IP. Unfortunately right now I do not have the $$$$.

As far as tweaking it now? Uh, uh. No way. I am happy with the way it is now. Don't want to risk anything. I plan on driving this car another 200 - 300K miles. Then rebuild the engine and drive it another 600K miles.

Between the two diesels, that will be a long time away!
