This felt much better. I did 3 WOT pulls to see how it averaged out. No knocks were seen on any of the pulls or during the 30 minute datalog.

Okay good. I put you at 32* cam rotation in the midrange and you didn't like it, now at 28* it feels better in the midrange. It's same same fuel map, but shows that too much rotation isn't always good. The best midrange we had before was at 25*, for this next one I am going to have you try it there to see if we can get some midrange back. We did change the intake between Rev04 and now, so that could be part of the midrange loss, but I'm not sure. I went ahead and used the cam angle map from Rev04 up to 6000 rpm based on your feedback to see what you think. Rev04 was a bit of an outlier anyways, maybe that pull was downhill slightly. But I want to make sure you're happy with the midrange, well all over honestly, but you know what I mean. All of the fueling was great, and no knock, so see what you think with this cam angle map and we'll go from there. Just let me know if you like this one, or the previous one more. Even swap between 17.1 and 17.2 if you want over the next few days and test it out.

Ok, that makes sense. I'll switch between these 2 calibrations and see if I can feel the difference. I think REV4 might be a little skewed from being slightly downhill. It was on part of the highway that is on a downhill slope. To "rectify" this, I found a great spot that I am able to do a 3rd gear pull without having to worry about traffic or whatnot. It is for the most part flat, but it has a slight incline. Its the same exact spot I've used for the last 7 or 8 WOT 3rd gear pulls. Thats why the 3 WOT pulls in this last datalog look pretty consistent.

Yeah see what you think between the two. I was starting to think it must be skewed based on the torque number and the dyno plot itself, but since you mentioned a similar feel in midrange power I wanted to address it. I figured you must have found a good spot because how consistent the pulls were, so that's good. It must be a pretty flat and relatively smooth section, or at least it works good for VD pulls.
Anyways, see what you think between the two and let me know. If you see any knock, post the datalog so I can take a look at it. Other than that, see which one you like the most, and we will make sure that one is dialed for you to run in the future. You may not notice a massive difference between the two files, but see if you do.
