hey i was still wantin to know what percent you programmed the vgt to close when off throttle. is it possible to close it down more or not?

it's actually a back pressure table in percentage, went up to 200% back pressure.. i suppose i could up it further if you'd like.

ok so if it wer closed down as far as it would go what percent would that be? obviously thats too far but maybe another 100 percent. or what would you suggest?

well consider this..270% is generated by the turbo at WOT at 3600rpm with a duty cycle of close to .1...which means very close to fully closed.

If you go much further than that you could get some surging on decel.

be careful with the bully dog stuff, when they restore the backup i have heard there are problems when switching to another programmer. Word was the bully dog does something to the backup file causing a no start when trying to program with another tuner.

Don,

Could you set this turbo brake setting in the options area on the predator like the speed limit option in the new crom file? I would be interested in a turbo brake. I imagine that this is a custom tune but with which hp tune? How effective is this brake or is it just for sound?

probably won't become an option unless a very large support was shown for it, i have no problem making a custom tune for whoever wants it though, just send me a copy of your original backup. As the author said, it builds back pressure off the gas which will slow you down.

Hey guys. so how do i send you my ori to get this turbo brake tune? i have a six speed stick and wonder how much it will help with braking.

IF you already have a tune on the truck, take the pred to your pc and hook it all up. Open DSdownloader and let it find the tool then hit the export tune from tool, it will ask if you want to export your backup..say yes and send me it
