...not good.

I lost about 60-70 ft. lbs. through the low end of the power band.

It's pretty rich, and I think Ed pulled too much timing after I told him before I was having cold-weather detonation issues (which I've attributed to my old air intake - haven't had that problem since installing the JLT). After 5500 RPMs it did improve over my old numbers, though, to the tune of about 30 more peak horsepower. Final numbers - 489 rwhp, 450 rwtq. I'm about to email Ed the files from Walker's, and we'll see what it does with a new tune very soon...
