Bishop..... thanks for the reply. Just a built (internally) 7m, flowed and blue printed injectors (stock) from RC Eng..... and a Holset Turbo off of a dodge truck. I am using the stock waste gate from Holset with a stock CT-26 wastegate actuator grafted on. It boosts fine and starts out at 6psi but after a few seconds of pausing.... it just keeps going and going then FUEL CUT! All stock fuel too.

Sounds like that turbo isn't built well for this application. It's probably a poor wastegate design. If the wastegate hole is smaller then the ct-26 then you could try porting it out, but it's not an exact science and you could end up ruining the turbo, you'll also need to keep the wastegate flapper bigger then the hole. It's nice to be different, but sometimes different is a hard road, I suggest switching to a turbo that we know won't have the same problem.
