Help me tune my 12.XX stang.

Hi!
I need a tool to help me tune my engine.I know that the LM-1 with RPM converter is popular.
But,will i be able to tune my A/F ratio only with this tool,just buy adjusting the fuel pressure and timing?
Or will i absolutly need something to tune my EEC?(tweecer,PMS...)

The only real way to change your a/f is with a tuning device, a chip or a ford motorsport extender. I use and prefer the anderson PMS.

Judging by your times a tuning device might not gain you much but won't hurt.

The big question about the chip:

How do we choose it???

if your "done" with yoiur combo, i would get a dyno tune. talk to your local dyno shops and see what chip they recomend. if your gonna go wtih a nitrous setup, get the delta diablo chip, its the 3 bank setup. otherwise, they should be all about the same.
