New problem:
On my drive home today I got E2 followed by E8. I turned the car off, wondering if it was just a sensor overheat (a problem I have not had since installing the heat sink). After a short while, I started home again, staying out of boost. I got wb readings for a minute, then E2 then E8. Repeated a cool down. Got a drink for myself, started home again, staying in light load/high vac. My xd showed E8, then it HCL (heater calibration). It did the heater cal, then it did a o2 cal. And now all I get is E8.
Ideas?
The sensor is in a new DP, but is roughly the same distance from the turbo as it was before (it's right before the flex pipe)...

Did a complete sensor calibration and it's up and working again. I also regrounded the heater ground for grins and giggles. Biggest shocker was the LC case was starting to distort a bit from the heat. In fact, it warped a bit making it tough to pull the sensor harness out of the LC. I plan to wrap the LC case with heat wrap, but didn't have time then, so I just folded one of those silver heat blankets around it. Good enough for now.
Jerry @ DIYAutotune went well above and beyond trying to help me with this, I didn't even purchase my LC1 from him! Guys, if you're getting an LC1, I recommend you give DIYAutotune consideration. Their tech support (Jerry) was better than the support I've received from Philipe at Innovate.

I had to be a rebel and put mine on the brake booster. The ground looked fine, I stripped the wire back and re wrapped it to the bolt just to do it.
I'm wondering if the problems were caused because the LC unit itself was over heating? I had the tony pipe on (boost was 15 psi spike dropping to 10
) and no heat shield over the turbo. And it was basically right next to the downpipe.
On that note, I did NOT adjust my MBC. Before with greddy pipe, cat, and muffler I was holding 8 psi pretty steady. After with tony pipe open to atmosphere, 15 psi drops to 10 psi. I couldn't fuel it correctly though, even with the MBC at its lowest setting, so I'm back to WG for now. Hopefully Jerry @ DIY will be helping me out with this though.

I ordered my LC-1 tuesday morning from DIY and it came in today. 2 days delivery time was great. I went with DIY even though I could have gotten it locally for the same price or off ebay for 20$ less because I love what they are doing and know they will support the product if I have any questions. Hopefully tommorow the isntall will go fine.
