I hate even talking about tunes because it go sooo many different ways. But golly! I switched from ppei to mark and I should of done it way sooner, trucks an animal now (built trans tunes, stock air and fuel) I can't wait to get new turbo this winter! Still undecided yet, your videos are driving me crazy lol!

Coming from that tct lly I like this setup much more. I wish I had marks tuning on that vgt though.. I think Ppei had my vanes to tight. I hit 52 psi with this 369 in 5th

TX of course
I'm guessing with your change in tuners you might know why else your VVT was slower....

Ya I don’t think Kory was letting enough air through. I was hitting 38 psi on my factory map sensor with that vgt. I’ll bet drive pressure was through the roof, could also be why that vgt broke the shaft too.

The whistle does sound great! I’m going to miss my truck during the winter.

But I have been thinking. Would a 369 make a decent valley charger for triples? Or would it be to small? Maybe do like 2 364s feeding the 369.

They used their 63.5 drop-in VGT in the valley, and 363s feeding it. 369s have been used numerous times already for the valley charger...

Huh, very interesting. I wonder how much power 2 363s feeding a 369 would be good for? Maybe I should talk to mark and stop cluttering up this thread.

Not very likely to that would be pushing them very hard. It’s not completely impossible but its not very efficient trying to do it that way.

Would 364.5s instead of 363s be better? Or at that point isnthe 369 holding things back?



No forced induction is 100 percent efficient. At best you probably would be around 75 percent. With that said to get closer to your goal it would take some good 366 chargers. Remember the bigger you go the less ideal it is for street driving. In the end it is your total package that is the difference maker and not the sum of the parts.
