is the factory wideband O2 sensor the one that goes into the stock cat?
if it is, i still have it, and the AFR the cobb reads is different then the one i have on my aftermarket AEM wideband O2 sensor!

5 is good.
Correct, the Cobb reads the factory wideband sensor. This is the one before the stock cat. There is also another factory sensor behind the stock cat but that one doesn't really matter. It also sounds like you have a 3rd O2 sensor (your aftermarket one). That one doesn't really matter either.
The factory PCM needs a good reading from the factory front O2 sensor in order to run correctly. Do you have the factory front O2 sensor connected?

the equiv ratio also does not change on the cobb. stays around 14.6 +/-2. my afr on my aem shows that the car goes really rich everytime i let go of the gas for a split second before going back to normal.

It sounds to me like you don't have the OEM O2 sensor installed. With the Interceptor you don't really need it because it controls the fuel and timing. However, when using the Cobb to control the fuel and timing you need the OEM wideband sensor installed before the CAT so that the PCM can see the airfuel ratio. Do you have the OEM wideband O2 sensor installed before the cat?

for the greddy kit i had to take off the stock exhaust manifold and there was no where to put it in after. was i supposed to make a hole for it? looking at my stock manifold, there was still a sensor there.

The Greddy turbo downpipe has a hole (O2 Bung) in it for the OEM wideband O2 sensor. Is that where you have your aftermarket O2 sensor installed? If so, remove the aftermarket O2 sensor and reinstall the one that is in your stock exhaust manifold. That should fix your problem until you can have another O2 Bund welded into your Greddy downpipe or Cat for your aftermarket O2 sensor.

That doesn't sound very good. My friend is an expperienced drag racer and his 2008 Mustang GT 5 speed (Currently stock) barely beat me before the Cobb AP tune and the Mazsport ignition. He is afraid that I will beat him now that I have the ignition and next week will have Cobb AP. He got me by about 3 cars from a 40-115 mph. At the track he ran a 13.60 @ 103 mph.
Cobb can add 10-15 rwhp and the Ignition adds 8-10, so with up to 25 more rwhp he will be in trouble
I will dyno after I get my car setup right with the Cobb. I can compare the two upgrades to my old exhaust and K&N drop in dyno.

Its a run for the money.

you know what, i just checked
i just jacked up the car, and the O2 sensor is there, with blue black and white wires.
i dont know why the stock manifold still has a O2 sensor on

My flywheel made bigger difference as far as responsiveness. and the cobb followed.. the ignition did some but not very much.
I beat mustang gt's I beat 350'z
Srt's dont beat me by much
that 0-60 was at a slight uphill with wheel hop and how humid texas day and not really trying.
my friend with his gt doesnt want to run against my car hes waiting on his nos lol hes afraid..
but my friends little civic is quick it will beat your 8 and you frien would prob only beat him by like 1.5 car lengths or 2 if he gets lucky.
DRAG RACES dont take much SKILL

Well I have been on the current map for a few days and all is looking good. Just to make sure a LTFT of -9 is negligable right? Or should I go to a 4b map? I remember MM saying ignore LTFT after a few drive cycles as long as it's bellow 12.

thanks
