currently i am running about 8-9psi depending on how high i let it rev. before i shift. But i dont recommend stock injectors and high boost. the power isnt worth the thousands in $$ of repairs not to mention down time and withdrawl. Im running a 250walbro pump and larger PE injectors to support as well as a custom flash. I did not install the Ati fuel unit/s to bulky and a flash with larger injectors etc works better in my opinion.

 

I am running 7lbs. with 380cc injectors and no problem.

 

thanks guys,
