Well the pinion angle was still off... enough at 90-100mph to shake the turn down pipe completely off the left muffler. now they don't match.
I think I need a new "magnetic angle locator". Finally put the trans back to where it was originally, and used just the 3.5* shims w/o the 1/2" drop plates. So its the trans angle is back to where it started and with the rear shims it feels a lot better.

gauges are in....not all working tho.


So......after completing the rear end adjustment yesterday, I loaded a fresh tune (my tuner sent to me yesterday) today for the ecm/tcm via hptuners. I am so glad I bought this program so all I have to do is take a scan or two, and send them to my tuner via email, who after reviewing them creates and sends me a new file with tune adjustments. I'm on re-tune 4...plus the original...so you can see that doing ecm tunes via USPS or even UPS/FedEx/etc would be time consuming and begin to get costly. You just can't beat being able to get a new tune file and installing it yourself.
So.............. I was on another "short" shakedown run and OMG!!!...I think he has the WOT part of the tune nailed or pretty darn close! It sure got my attention when I gave it the boot and let it go...it kicked the truck sideways enough that I had to get out of it. I think its even pulling harder now then it did with the carb setup!

If I don't break something on test runs around the house...I'll take it to the track this weekend...with the GoPro and the camera...to record some of the action!
