ok. i am kinda stuck here. i got about $300 and i want some go fast goodies. see my sig for current mods. i am thinking about either doing nitrous, or getting some fuel control like an safc. or maybe a pressure regulator and a gauge. can all you gurus out there give me some advice here? also, i am having a problem with my tps. i have measured everything to be fine with the multimeter, and the check engine light is still giving me code. i have reset it too by disconnecting the battery. any help with either of these would be a great help.
thanks

 

Maybe a header? If you don't mind the noise...

 

i already have a header. sorry, that is not in sig. here are the full list of mods:

header, presilencer, old style racing beat catback.
magnecore 10mm wires
street ported rebuilt motor
lightened flywheel
hks air filter

 

Ok, the next biggest HP gain is probably nitrous for that price range.
