Well, I am extremely pleased with my logs that I recorded tonight. It was 75 degrees out with some humidity when I did these runs. This was a 2nd thru 4th gear pull which ended at 125mph in 4th gear. I was boosting 17psi which dropped to 16psi basically right away. I used MCCC about two months ago on the top of my piston heads--did the soak thing. Then sucked out all the crap with a vacuum. I'm sure this helped with reduced knock. Also, I added half a bottle of water wetter a month ago to the 70% distilled water, 30% dexcool. Even at 18psi, the car still feels strong. I also logged my Injector p/w and it never went about 93%. Although above the recommended 85%, I don't have money for injectors Thanks.

First off, I would post up the whole log, just not bits and pieces. Your second gear log starts at 5700rpm. What about 3k-5700?

Also, do you notice your timing decreasing at the top of each gear?!!! That's not good. Although you aren't getting knock (which is good), I have no idea why your timing is falling. I wouldn't feel right if that were my log.. :(
 
My timing does the same thing, it's at 22 degrees of timing around 6200-6300 rpm's, and then declines to about 16-17 degrees by 7800 rpm's. And my car's always done this, so, I don't know if it's a 1g thing, or if thats really not right and vlaar and I have something wrong with our cars, feel free to comment.

p.s.-that 16-17 degrees of timing is on the 14b at 16 psi, with little to no knock. Consequently, there are times when knock randomly occurs and it's still at 16-17 degrees of timing at the same RPM's. Just a little FYI.
 
If you look at most people's logs, timing always drops off towards redline. How could I correct this so to speak? Thanks.
