You do not get hp from adding more fuel. You need to add fuel accordingly to how much boost you have.

Yup. More fuel is only half the equation. You need more Oxygen, or air, to balance that.
oh ok yep make sense... so boost controller, more fuel, and AFC? and how often should i change the spark plugs, been driving the supra for 10 months so far...
Did you change the plugs when you got the car? And it all depends how much and how hard you drove it for those ten months. If I was gonna be trying to make more power though I would probably replace em, be on the safe side.
Depends on which plug and how many miles. Coppers 5-10k depending on how much boost and how often.
ya i changed it when i had it swap, and i do beat on it once in a whle, and i drive alot... how many miles should i replace just incase?
I replace them when I notice them missing at idle, or I notice it getting a bit "sluggish" than usual. Seem to be lasting a long time at 27PSI everyday, though.
hmm i c, i used the ngk ix iridiums on it... i am noticing a lil less gas milage, so ima swap em out.
