The potential is there. Ive had a small taste of what it can do but until I figure out what the hell is causing my phantom KR I cant tune any further. It only happens when I accel and the engine torques. Something is tapping somewhere and Im still trying to figure out what it is.

So far, Ive been under the car twice after the install. Once to adjust the WG and the second to recheck and tighten all the bolts just incase there was a small leak. Then I did a boost leak test and found and fixed a leak. Then, a friend fabbed up a bracket for the CP because it did not line up with its mounting screw on the IM to keep it from flexing. I thought at first it would be okay but found that under load the cp was tapping the fuel line, hence the bracket to keep it in place. Then I adjusted the intake cause I found that it was contacting the fender well, and although it wasnt causing issues before I wanted to eliminate all possibilities, so, I put a large piece of foam padding under the intake so it would not rub the fender well anymore. Then....lol...I took the intake mani off to gain access to the KR sensors to adjust then to the 9 o'clock position like others have said to 'de-sensitize' them. The very last thing Ive done is replace the o2 with a new one because I figured maybe that was going bad and skewing the readings and actually causing me to run lean. It was a good idea because it looked shot when I took it out. After aaaaaaaall this, I still have the KR on throttle tip-in though not as severe after I replaced the o2.
Now you guys know all my business lol
I havent heard from any of the other 2860 guys.

Its only on initial throttle tip-in. More in first from a stop but it registers in all cylinders lol Nick is taking care of me for sure! Thanks to his suggestions Ive found some issues that needed adressing 
LOL
Hell, it could be one of the lines I had to modify vibbing against the block for all I know! Short of putting a camera down there while I drive to see if its happening...I may never know haha
Its cool. Ill keep troubleshooting till I get it resolved

First, gotta get the DP "gasket" thing fixed (this is the hardest part and I don't know how long it'll take).
Also need the elbows beaded (get Dejon to do it, and get them to re-angle coldside IAT by building up for a new screw hole and drilling/threading it).

Figured it was time to revive this thread
Tuning is going well now that we've got some issues sorted out. Nick BYT has me on some cool new changes he's made to his tables and first gear is great now and everything feels nice and smooth
We just started working on adding power at WOT now and will be trying my first power revision tonight
