Ok well I have all the mods in my sig plus a built tranny,shift kit , and 3500 converter. I also have a cheater system that will be installed before San antonio. I just wanted to see what else I can do to get a little bit more out of her besides putting heads on it. Will I need new in injectors?bigger tb? Intake?give me some ideas of feels like there isn't much else to do.t

 

what type of CAI????

 

K&n.....

 

get a better intake system! A system with a box will reduce IAT's and make more power. Also you can add a ram air with a box
