Help! Need E-tune/remote tune support | 350z HR Stillen Supercharger

[NissanTracker]

I was originally getting tuned from Kaizens in the Boston, Ma area... but they have since closed. Brought my Z to a shop that was on UpRev's list... and just a horrible experience. Car doesn't rev past 2.1K rpms, Idles like garbage, and had to tow it have not even a mile of driving.

Since I can't find a reliable shop anywhere, I'm looking for an e-tune/remote tune. I have an 07 350z HR, Stillen Supercharger with UpRev. Mods below:

Stillen supercharger kit (default pulley)
Hi-intentions high flow cats
Motordyne TDX2 exhaust
Frozenboost a-w intercooler
Turbosmart dual bypass valve (vent to atmosphere)
modified intercooler pipe with MAFs close to the TBs
25 row themostat controlled oil cooler

On my first tune with this kit, everything was great, minus a p0300 that was showing up once in a while. Almost guaranteed to show up on a cold start. Bad experience happened when I changed the intercooler pipe to have the MAFs closer to the TBs and vent the BOV to atmosphere.



A little recent history:

Idle surge after Stillen supercharger install

Advice new style Stillen S.C. Intercooler pipe (MAFs at TB)
