I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

Need some help - G8 PATC Phoenix level 4 kit

Hi guys,

New to the site. I've got a 2009 G9 GT with a built iron block 404 with a Maggie 1900 supercharger, makes 700/720 on 93 octane//meth, and 750/780 on e66/meth. The trans has been built with a PATC Phoenix level 4 kit: https://transmissioncenter.net/shop/6l80e-6l90e-phoenix-super-master-kit...

The main issue I'm having is that it bangs the rev limiter on wot shifts. I've tried multiple different TM settings, mph/ and rpm settings for wot, shift pressures and times. Nothing has seemed to work. Just to get this trans to act right during normal driving I had to increase the oncoming and offgoing pressures and volumes quite a bit. This it the first one of these kits I've tuned so I'm not sure if I'm heading in the right direction and I really don't want to damage anything in power. Or maybe if there's an internal problem with the build and that's why it's acting this way?

I've attached some logs and the tune file. Any help would be greatly appriciated to get this thing shifting like it should.
