Lower my fuel pressure to help w/fuel injectors.., ...being too large??? Options

[Mueller]

Running 2.0 injectors on my stock 1.8, new fuel injection fires all 4 at one time (batch), I have a feeling new injectors are too much....anyone lower their fuel pressure to compensate for large injectors??

I'm wondering how low can I go yet still retain a nice reliable pattern?????

GM tbi injectors often go "static" - meaning they stay constant open because by the time they might close they are opening again because the fuel needs still havent been met... we've had a lot of problems making power with the system. They go static pretty quick because they are such large injectors and they take so long to open and close. We've used vacuum adjustable regulators so that fuel pressure is low at high vac and high at no vac. The pressure has to be increased at WOT and pulse width messed with a TON so as to still correctly meter fuel down at low rpm, while at WOT they can go static and be in full open but still delivering the right a/f ratio for peak power.

Mind you these small block chevy engines are running about 350hp+ with only 2X80lb/hr injectors at twice the rated fuel pressure.

I thought you guys were referring to tuning the stock djet system. I was getting excited for a moment thinking that my old prom burner might come into use again LOL
