Im just saying, maybe if you typed out what your saying a little better, it would be easier for someone to help you.

I dont think i can help you because i havent dealt with my car hitting the fuel cut yet

First you need to find out if youre truly hitting fuel cut.

You need to pull your trouble codes.

In the engine bay theres a "diagnostic" terminal. You need to open it. On the top of the lid is a diagram. Bridge TE1 and E1 together and turn the ignition on. Dont start it, just turn it on. Check engine light will flash in a series. Example: flash, flash, PAUSE, flash, flash, flash would be a code 23.

The codes will cycle through and just repeat. Once you get to the same code twice youve read em all. Read em, write em down and post em here and we will tell you more than we can now.

If it falls flat on its face 99% sure it is fuel cut and if that is the case you could be spiking so turn down the boost or rmeove the boost controler and let everything go stock.
