MY CAR HAS BEEN ACTING VERY STRANGE THE LAST FEW DAYS. WHEN I GO TO START MY CAR IT WILL IDLE FINE, BUT WHEN I GO TO PRESS ON THE GAS HARD IT WOULD LEAN OUT AND DIE. THEN AFTER IT IS WARMED UP, IT WOULD ONLY IDLE FOR A FEW SECONDS THEN DIE. WHENEVER I BARELY PRESS ON THE THROTTLE, IT WOULD REV UP UNTIL THE VACUUM INDICATED 0 ON THE BOOST GUAGE AND DIE. AFTER MESSING AROUND FOR ABOUT 10 MINUTES IT WOULD IDLE FINE AND REV FINE. THIS ONLY HAPPENS WHEN MY CAR HAS BEEN SITTING FOR MORE THAN A FEW HOURS. MY CAR WOULD ALSO LEAN OUT AT WOT WHEN HITTING BOOST.

do you have a missing link for your map sensor? Because if you dont your car will missfire when in boost, thats why you think its leaning out. With a 12/1 fmu you should be running super rich. Are you sure that you have the right fuel pump? whats your fuel pressure at idle? atleast 40psi. is your fmu hooked up properly? make sure its getting enough vaccum.

I HAVE THE MISSING LINK HOOKED UP AND THE FMU IS HOOKED UP CORRECTLY. I DON'T HAVE A WIDEBAND SO, I DON'T KNOW IF I'M GETTING
ENOUGH FUEL IN BOOST. AS FAR AS THE PUMP, IT'S RATED AT 255. I DON'T KNOW IF IT'S A HIGH PRESSURE PUMP THOUGH.
I JUST TRIED TO START UP MY CAR AGAIN, AND IT'S STILL GIVING ME THE SAME PROBLEMS. IT WOULD START UP AND IDLE LIKE IT WAS FINE. THEN WHEN I REVE IT TO 3500 IT WOULD BOG OUT AND DIE AT FULL THROTTLE. BUT IF I BARELY PRESS IT, IT WOULD REV FINE. IT'S ALMOST LIKE RIGHT WHEN IT TRANSITIONS BETWEEN VACUUM TO PRESSURE IT DIES. WIERD.

you really should take it somewhere to be looked at before something burns up
