they add more fuel to the fire. i wouldnt recomend them if you dont have bigger injectors, timing, fuel plate or turbo. even for the mods i have there a tad more fuel than i need, even with your injectors and stock turbo i dont recomend them

well they will deliver more fuel than you stock ones will. yes you will have a gain in EGTs but not near as bad as the 191's do. you will notice a bit of power gain, yes it is hard on the trany but any aftermarket upgrade is, i forgot do you have a auto or 5speed
