i installed the little black box from the star kit and for about 9 or so months nothing wrong. one day when i would hit boost it would fuel cut bad and at ideal it was wanting to die. so i took it off just so i could drive with out it stalling. when i took it off all back to normal. i can boost and everthing. i thought with it off my car would not run right. runs better with out it. car 99'gs 10th

If you ease into boost after 2 sec your car will throw a CEL and react to the map voltage being over 4.7V. The Star black box is notorious for going bad which is why a few of us use the Missing link or a Custom FCD.

so my timing and everything is going down the drain

you can get away with boosting every now and again but eventually your ecu will see the boost and you will get fuel cut. you need a missing link or fcd with a 1999....

i have a spare fcd if you need one, PM me if you want it.

so i have a safc and would i still need a fcd? and if i use a safc do a make my fuel pressure at a solid number or rasing right now its rasing.

yes im pretty sure if you have the safc you still need a fcd, some way to not let the ecu freak out under boost. Of course I don't have either of those so I can't say for sure (thank goodness for 95's)

Yes, if you're not a 95, you need a FCD or ML. Even with the SAFC.

100% correcto.
