Friend of mines have a 09 V Twin turbo car Ive been tuning we've had zero issues with lockup on the stock converter until the triple disk circle d swap. We've had the converter pulled and sent back to circle d where they found no issues with it and got it back in again with no lockup.
Car will show TCC line pressure but will never lock. Attached is a short log and the tune file, we've tested a ton of different pressures and apply points with no luck, ive never had issues with a 6l90 or even 80e car with tcc lockup.
Yes I know fueling needs some work we changed the engine/cam combo along with the converter but want this thing to lock before we go any further
