bigger injectors, less fuel pressure

 

hey well i say bring the fpr to 54psi and use better gas .what oct you useing now? and what injectors? whats your timming at ?

 

Make sure your timing is correct. Use better gas and upgrade bigger injector.

 

2 liters need a lot of fuel. I would get some 370cc injectors.
