i am on the site so i don't know what you are talking about.

 

in before the lock!

 

he is telling you to use the search function since the question has been asked twice...or maybe three times. Also the question is pretty broad being no info on what gas, any supporting mods, etc.

 

car is stock except for 3in full exhaust and filter .

 

how about you take it to a dyno and turn up the boost on the dyno and see where the car is makeing good power and where it starts to lean out.
dunno what part of florida you are in but you should go here... http://www.provenpowertampa.com/

having a boost goal is doing it backwords.
