I am running the 275 injectors and an EZ, which of the three settings should I have this thing on to get the best performance? I do not care about smoke just power! LOL! right now I am running on the setting without injectors I think it is the far right one looking at the box. Also can I run without the box and just the 275's and not have any problems setting codes? Another question is when I upgrade boxes, should I got with a Comp, Hot Comp, JVD, or TST? I have no idea which is best. THanks for all inut.
