Hey James,
You can't expect RRE to spend hours helping you with your problem for free. You said you were just tuned by Btack. That may or may not be your problem, but there recently was some drama about him allegedly stealing tunes:

Not sure if it's true or not, but I personally would recommend you take it to an actual reputable shop and just have them do the work/tune. Sorry if you have to dish out money again for the tune, but that's what happens when you don't start off with a reputable shop/tuner.
The difference between a reputable shop, RRE or other, is that they won't say "we can't fix it so it's your problem now, go ask the internet on how to fix it."
Good luck with the car!
