I just ordered a JMS chip (custom, but not as custom as Capri306 is talking about.)
I should have it in a about a week with a trip to the local track a few day later. So, I should be able to give you my opinion on the chip soon.
Note, however, that this "chip" is one of my last mods (before the ATI ProCharger next year) on my Stang. I have heads, cam, TB, intake, blah, blah, ...you get the picture. I ordered my chip for 3 reasons:
1) My car seems to run very rich (plugs are dark and gas wet, exhuast about knocks me down, etc.);
2) I am very close to 12's in N/A and street trim form....and I really want to go 12's before I add the blower;
3) With all my mods, the car has, at times, idling issues (high/low, random).
And to be honest with you, I really think that wiht all of the components I've added, I really don't think I have the car tuned right. So we'll see what happens.
What type of mods do you have?
