Re: boost problem
 

How many pounds are you running? What are you using for engine management? What is done to the fuel system?

Re: boost problem
 

sounds like fuel cut

Re: boost problem
 

Fuel cut...... if you have an electronic management or an EBC. Get your set-up tuned!

yea stock ecu with stock injectors running a fmu with a aem fuel rail and missing link....so should i upgrade my injectors to a 450 or 550??

Re: boost problem
 

Are you using any kind of electronic boost controller? Fuel cut has nothing to do with your injectors. Fuel cut is the same as boost cut. If you are using an electronic boost controller (EBC) or a some kind of electronic fuel management that monitors boost, you could be hitting fuel/boost cut.

For instance, if your wastegate is set at 10 psi but you are spiking boost to 14 psi, your EBC or electronic fuel management will see that boost spike and control (cut-off) fuel to drive your motor slower. This is a safety function so you do not blow up your motor from overboosting.......
