Default Mod questions...

I am thinking of adding an 18% lower, LTH WITH cats, an intake (probably haltech), and a tune. Will the injectors handle all of that? I do not want to do meth or nos or E85.

Yes. With out E or Meth however you may run hot. You may want to invest in a few cooling mods.

Yeah I will do some cooling mods as well, just want to make sure the performance list is right first.

Why do you say this instead of 18%?

Is there any official word on this or is it all just opinion? I've seen people using 9%, 15%, and 18% without meth, so is there any definite answer on this?

Multiple 18% OD with bolt on cars have lost fuel rail pressure up top. That all I can speak from. You need meth, but hey try it, you can always buy meth injection or another motor later. J/K Seriously there is a point where driving the blower too hard creates MUCH more heat which requires timing to be pulled, decreasing power.

You can always go to a 15% from ATI or LPE

I'm not against the idea of going with 9% or 15% instead I'm just wondering what I can run without any meth/nos. I am just hoping to hear what my options are.
