I have a 3rd gen with RB exuast single turbo, Wolf3D computer, front mount intercooler, Greddy boost control and timer. When accelerating to 4,500 to 5,000 car seems to hit brick wall in 2nd gear and upper gears. That happens if the boost cut is turned off on the Wolf3D but not as bad. Could some help me solve this problem before I put money into new Injectors and fuel pump. Not sure if fuel filter has been changed

 

I don't think you can run stock injectors, or stock fuel pump, with a single turbo, unless you are running very low boost.

 

What are your AFRs doing when it cuts out?

While it's not the direct solution to your problem, I agree you really should invest now in injectors and fuel pump. No point in running a single if you're going to run it under the power limits of the stock injectors and fuel pump. Not unless your tuning time is free - and no good tuning is free.

Anywhere from 12 to 14 a/f ratio

 

What size injectors do you recommend? I'm running a Garrett T04 its max boost recommended settings is 15psi and max power is 350hp.

 

Id get a bigger fuel pump for sure, i had a PFC DP MP cat back, and was hitting fuel cut. All i really needed was a FUEL PUMP and i probably wouldnt have blown my engine So id do that 1st.

Im not sure how good the Wolf3D is, but i might upgrade to a PFC, more info on it.

 

Have you tried posting in the Wolf3D section?

I think you have several problem, depending on what's on your car. Looks like you have either a fuel or tuning issue (or a combination of both).
