Okay so heres a question. I looked everywhere for this specifically but to no avail for my situation. Technicaly if you raise the fuel pressure slightly higher than stock levels (5-10psi more) and your injectors work in the area of 80% duty cycle then you should get better atomization and better combustion hence more power. correct? I'm guessing that the stock 550cc injectors on the evo work lower than 80% duty cycle when at WOT (80% being the general rule of thumb for ideal) so If I raise the pressure just a tad. It could give me an edge on a stock evo? what do you guys think?
oh yes, just to let you all know I'm basically still stock looking to mess with a little better fuel tune later after I get my full eghaust system beefed up with a flash.

 

ideas? questions? answers?

 

bump for some insight...

 

No and no.

Injectors are designed to give best atomization at a certain pressure differential, and that differential is maintained by the FPR. This has nothing to do with duty cycle.

Raising fuel pressure slightly results in no performance advantage. The ECU detects the slightly rich condition in closed loop operation and compensates its fuel trims accordingly to correct it.
