If you want good spool you will need twins. 600-650 is a lot to ask of any signle on a vp44, the vgt can't do magic.

I love my VGT to death, but for your goals I would never recommend a vgt turbo. You need twins.

I see i also have a feeling that it could be a 66/71. I will take it part and remeasure it. I was gonna try 7x014 sticks to see how hot it would be... worse case i turn down the quad right? If timing is set to 10 degrees and pump stretch is lowered i would think it would shoot the fuel in before tdc so it burns most of the smoke right.

I also heard that 10 degrees timing on a vp truck is bad. Anyone know why? Its also stated in the quadzilla instructions

If you are going to try that you need the v2 tuning. You will not be able to control smoke with the older quad tunes, turning it down won't help. We have spent the better part of a year figuring stuff out thanks to the v2 tuning.

10* is 10* over stock not 10* total. It's too much regardless. You again need v2 tuning to control timing better, much better. Just add more timing to get rid of smoke won't work.

In short too much timing too soon causes issues.

You have a pulse v2 monitor or the v2 tuning on another monitor? There is a difference.

He has the pulse pv2 not v2 tuning.


Scroll down past the v1 section, what you have, to the v2 section, what you need.

Your current ablitly to control fuel and timing is not enough to control the setup you want.
