Bogging/stumbling and check engine light flashed three times.

Ok so I was in the garage trying to rearrange the FIC to fit in glove compartment better when I notice my passenger tire is completely flat. So I leave the FIC where it is with everything plugged and start the car it starts fine.
Back out of the driveway leave my area and reach the light. It turns green I give it a little gas I notice a little hesitation but don't think much of it. (Mind you I'm low on gas but not empty yet just a little before empty.) I reach the station put air in open the hood to check on everything it looks ok.

Leaving is where it gets hairy first gear short shifted it no problem, second gear immediate bogging/stumbling, go to third same thing now the check engine light flashed three times which got me scared as heck so I hurry home and park it.

I'm on 370cc stock inj,50 trim, 5psi, and partial MAF based street tune due to faulty MAP sensor and crappy pipes that keep blowing off.

My theory is that I'm now leaning out due to low fuel and the tune is trying to add fuel and there is low quantity. I glanced at the AFR gauge is was about 14.0-17.0 when I was trying to give throttle. I'm going to gas it up tomorrow and hopefully that solves the issue. Also I'm getting a scangauge ASAP.

Please add your opinions that would be most helpful.

Find and fix the vacuum leak first. Then upgrade your *320cc* injectors before you get into full boost and blow your engine. The FIC can only add as much fuel as those little oem injectors can supply and with the stock fuel system, it ain't much. Not enough for 5psi even. I was seeing 95% IDC on 440s at 7psi.

Also, spend $20 on a small 12V air pump so you don't have to drive to the gas station on a "completely flat" tire next time.
