Hi guys,
I have a 2009 G8 GT with a 404 and a Maggie 1900 blower, PATC Phoenix level 4 built trans and billet 2000rpm converter. Car makes 750whp/780tq. My issue I'm having with it is it just blows through the converter and bangs the rev limiter and doesn't shift. If I lock the converter through HP Scanner, it'll shift nice and clean. So I've been trying to get the converter to stay locked on WOT. No matter what I put in the TCC tables; normal, pattern A, and WOT, it'll command the converter to unlock on any significant throttle increase. I even have shift lock enabled. Is this something that hard coded into the G8 TCM, will in not lock below the factory 95mph in 4th on WOT?
Thank you for any input.
