cobra computer is calibrated for 24lb injectors and with your mods and even with the ported gt40 heads you don't need to switch to 24lb injectors your not making enough power to warrant it so sell the cobra computer it's got lame timing curve anyways

You need more air before you need more fuel

and ignition upgrades may make the motor run noticeably smoother, but no power advantages

track heat isn't THAT good, but it will work fine with your combo. The heads are the bottle neck so your missing a hell of a lot of air. Do the gt40's, upgrade the springs, or don't even install them. Your def not going to invest in a custom cam so I'd look into anderson cams. Call them and tell them your intake and head combo and they can pick a good shelf grind for you. Get some gear and call it a day. You go that route and it should sit nicely in the 12's.

lol

take a totally stock 87-93 mustang and drop the fuel pressure to around 32 psi and you'll gain hp.. i know because i've seen it and have done it a few times. Leaner is meaner to a point. Just like anything too much of something is not good just ask Ron Jeremy
