My next step was to install fuel block & fuel pressure gauge/as I thought maybe pump was getting weak...but this is where the rpm's peaked in 2nd & manually up shifted to 3rd...same thing. And was stuttering & weak.

About 600 miles ago.
poor picture quality is from the vibration from the stuttering....as this happened on a Friday & had me sick all weekend running test's on it.
