So is anyone running a jet performance modual on their 2.4l's I have a cold air intake and flowmaster on mine so I was going to go with the stage 2, I already run high octane in it so thats not a prob, I just want to know if it really makes a 259.99 dollar diffrence? plus I just bought a currie anti rock so my funds are spiriling downward, quick fast and in a hurry!
