Installed dsp5 and have my selected tunes set for selected number on my 2007 lbz.

But I've got setting #2 as my tow w/turbo brake.. which works when I start the truck and it's been sitting. But after I drive around for maybe 5-10 min it will all the sudden quit commanding turbo to 100%, still with it in tow/haul. Iirc it will show around 50%... What could be the issue here? Brother who tuned it has a lly and his works perfectly fine.

One other question is.. adding a full vane position tune, either so at 0mph in whatever number I choose on the dsp it will go to 100% vane position and stay three until vss changes or tps changes. Is there a way to do this?
