fuel pressure question quick

[Faviolosky]

ok so my car has been a major headache in starts and randomly backfires, now i put a new ecu u in and nothing,
but i unpluged the fuel pressure regulator vaccum line and the car starts on the dime and has great throttle response, does this mean that i should get a new one or/and upgrade to a 3 bar, which i have the latter???

please is just a quick question which could save me 15 bucks a week on gas

Which M20? You should run the correct fpr for your application.

Unplugging that vacuum line will bump up the fuel pressure and richen the mixture. Check for vac leaks.

ok i put the three bar in anyways and the car is running really good, the backfiring and bucking is gone for good, i have been driving it fir three days now n no problem, every morning however it has not so good starts, cuz it takes a little long if i dont give it some gas, but other than that its good
