Yep and yep. Like I said I was already in 5th and only about 3.5k when I was rolling on. Around 95mph is when it seemed like there wasn't much more...., I mean I was still climbing just not rapidly.
However today I let 4th climb to somewhere around 6k about 95mph before I shifted to 5th, rpm dropped back to about 5.2 or so and kept on pulling strong, I didn't jet a good look at the tack after this but I backed off the throttle around 105. I still thinK you may be right about asperation at WOT. I've noticed that for a while, its not like to bogs down just feels like I have better responce before I get there.
