I wanted to thank each and every one who since last September helped to get me to this point where my silly car is finally fixed.  Every post and idea is and was appreciated over this 4 months ordeal of two intermingling issues that kind of masked each other.

You are Awesome.  Thank you. Were it not for the pushing from you guys in the last 2 days i might have done something drastic and given up.  patience ... is not my thing (whod'a thunk).

Thank you, and good night .. it's time for kid's skip-bo and chocolate milk.

I skimmed but didn't read in depth, as diagnosis is way out of my league. What ended up being the issue(s)?

His problem was the equivalent of trying to run his latest calibration on Windows 95' or Vista LOL Or trying to play a PS4 game in a PS1

Keep your devices updated!...Joking but may have been more than that also.

In his defense.. unless you are diligent about hooking up your SCT device often to check, you wont know there is an update. Additionaly, its a PIA to revert back to stock then update the device, and then reflash the tunes... SCT has got to find a better way to do that.

I think upon opening the device updater it notifies you if there is an update for the device and or device updater program.

It will tell you the device updater software needs to be updated, but not the FW on the device UNLESS you specifically run the device updater check. Even then, say you get a new tune update, you find out that the FW needs to be updated... you have to go back out to the car, reload the stock tune.. update the devices... load the new tunes... then go through the process of saving the stock tune again which takes forever, and then load the new updated tune. Its a freaking yank...

J,  it was two issues.  one was physical, the other doesn't make any sense (to me) but it was handheld-tuner related.

I had a over boost issue.  BAD overboost.  stuttering and trying to stall at 5000+ rpm.  the ecu would shut all spark off mid run.  it was super bad and hard on the car

Fixed that by replacing both turbos.  We think the wastegates were not actuating correctly.  After replacement the logs no longer showed massive overboost (18+ pounds!)

BUT the issue still happened!  but for a different reason.  My tuner went bad somehow.  The tunes (all of them including stock) still stuttered and freaked out but it was not over boosting .. so initially I thought the problem was the harness.  but on a pure bullshit lark ... i reset the tuner.

All the issues fixed instantly, Stock, light boost,  Max boost.  No more stuttering.

to timeline it with hindsight::
Car was running PERFECT in the summer of 17 on meth.
Started having wierd stuttering issues at high rpm off and on on like october.  But no overboost issues.
Went racing one last time,  had the best runs ever!
The very next morning the waste-gates were blown.
At the time i had no idea the wastegates were blown and thought it was the meth pump.
Spent a month fiddling with meth. 
30 days later, I gave up and reverted to a non-meth tune thinking it was too cold for the amount of meth i used.
*that was when the tuner went bad i think*
after reverting with the now bad-tuner i still had issues, brad said my waste-gates were bad.  (we had no idea my tuner just took a crap)
finally fixed the turbos but we still had bad stuttering we were all VERY confused as we did not know the tuner was funky
we looked at logs and everything was 'perfect'  .. the give away was we had BAD stuttering/stalling issues ..  but we could not 'see it in the logs'
I was about to give up when i was told to try resetting the handheld.
After thinking that was insane.. i did it.
next 2 datalogs look perfect,  car felt WAY better
after a few power cycles later,  it is now perfect.  resetting the tuner fixed the ecu/tune/handheld issue.


that's the timeline WITH 20/20
