Hey, I'm having some serious trouble getting my DSM running for the season. It was previously tuned last year on a weak motor by a really crappy tuning shop in waukesha, wi. Without changing the tune, or any mods and swapping a fresh motor in im having trouble getting the thing to idle. It's leaning out at idle, and IDK why... the car is put back together entirely the way it was before except it has a side mount with stock IC piping for now. I figure that really shouldn't change the tune drastically if at all.
Here's some info on the car
Mods:
Fuel Lab FPR, Walboro 255, PTE 880 injectors, 6an fuel lines from fuel filter to rail and return, Fuel Lab metal fuel filter, 16G big EVO3 turbo, 2g MAF, Injen intake 2g, 1g n/t accelerator cable cruise delete, stock B/V is to atmosphere for now, manual boost controller, AEM UEGO digital wideband, Autometer boost gauge(loose on manifold side cant get vacuum reading).
It's tuned for 93 pump gas right now, looking to go e85, but id like to drive it to the tuning shop, and im kinda short on money right now.
Here's a video of it leaning out, I'm keeping my foot on the gas here about 8% throttle to keep the rpms around 2k, but as soon as I let off it leans out and stumbles.

Attached is the log from right before this video, and the settings that were used. A friendly DSMER has already changed my settings ecu and direct access to what he believes to be better but I haven't had a chance to try them out. I'm thinking its more than the tune and maybe mechanical. I know my timing isnt set perfect on the CAS. I went ahead and ordered some TB gaskets as well.
Otherwise... ANY IDEAS????? I can't find a whole lot of ppl with this issue.
