VGT off?

stroker221 · Oct 27, 2014

I made a vgt switch and when turned off theres no more smoke than usual (awesomeness) and idk why but my truck is barely laggy at all. And unlike other people, I can't tell a difference at WOT between having it either on or off?... The only big difference is sound which is why I don't it but I didn't expect it to run nearly as well as it does. But with the vgt UNPLUGGED it was very laggy and not fast at all. I'm confused... But happy with it

At wot it shouldn't make a difference seeing the atmo is doing all the work at that point

That's what id think but alot of other ppl on another website say they don't have much power when they do it so idk.

can anyone give me a ballpark on the cost of a custom tune like the ones described in this thread with the VGT off at idle? I'm just looking for a ballpark before I waste anybody's time with a quote. thanks

i doubt the tune price will change, just specify that's what you want when you order...

Finally ordered my Gearhead tunes, $250 for the 6.4 Eng + Trans, $175 if your manual no trans file needed. Can't wait to get them in and requested VGT off as well.

I got the racetune from gearhead for $150

Does anybody know why when I'm idling, my vgt position slowly climbs? I set all my vane position tables to 2 under 1000 rpms and desired ebp tables to 0.

Gold engine high idle?

ckrueg · Dec 10, 2014

No, it happens when it's warm and the rpms stay at 650 ish

maybe this is a dumb question but wanting to turn off vgt under 1000rpm following td-5 graphs.. then i noticed he has diff turbo set up than stock as well as few other goodies i dont have yet...i am still running stock turbos..i wouldnt think this would change turbo vane control but possibly the ebp settings.. any insight would be much appreciated . i would kick myself for messing somthing up over myself just wanting a different sound.

As I started before.. probably a dumb question...and yes it was. Ive been watching my ebp on my mini max and have answered my own question. Under 7 psi till over 1000 rpm so obviously this wont be an issue.. sorry still learning and at a very slow rate apparently. And tables not graphs. My mistake as well.
