New turbo problem
So my turbo is on, i got 450cc injectors and a tune.. i asked the guy, "Do i need a new fuel pump? My pump comes in tomorrow in mail" and he said "nope you can run on stock pump"
So i put new injectors on, stick in the ecu.
Start the car, it starts up nice i guess.
Then when i drive it, it drives like ---- when i try to accelerate above 3000 rpm
And when i do go in boost (very little), it feels like its pulling VERY VERY slowely.
Could it be that im running on stock fuel pump?
And im also running 87 octane gas Or what could be the problem.
And i also didnt put the resistor box on.

how much boost are you running? did you purchase low impedence injectors? if you did, you need to install the resistor box asap as you can fry the ecm.
you always need to run premium fuel on a boosted application. running low grade will cause detonation and it will destroy your engine.
do you have a wideband afr gauge hooked up? if not, you need one to know exactly whats going on with your engine.

7 psi. yea 450cc injectors and i am running a resistor box on them. yes im running 91 now.
And the car pulls now, but it sometimes dies at idle, like if i press the break pedal or turn on the headlights, it dies in a few seconds.

check your alternator and battery to make sure they are in good condition. your alternator should be charging your battery at idle at ~ 14v. bring your battery into a auto parts store for a free battery check to rule out a bad battery.

Then thats your problem. Base maps arent meant to be driving day to day. They are to get you to your tuner so that your car can be tuned. And without the wideband your kinda unsafe. You dont knwo if your leaning out or flooding the motor with fuel. Both are very bad and can blow your motor very fast.
