ECU Question

[drdking]

I just dynoed my MSP today with very poor results, mainly due to my Air/Fuel ratio dropping way low early into the run and never recovering. I've known it was running rich for awhile, but I didn't realize how rich it was running. I've read a lot of posts about ECUs and programing but I'm not sure which is the best solution, while still being affordable.
So far I've done an Injen CAI, Apexi Downpipe & Exhaust, Turbosmart 2-way boost controller and Blowoff Valve.
The car was being used as a daily driver for a while but now due to buying a new truck it's primary use will be Auto-Crossing.
My main concern right now is buying new racing wheels/tires so I'm trying to find a affordable solution.

SplitSecond AFC to lean it out and get a wideband a/f gauge.

i dynoed my car about last august and all i had was the hardpipes with greddy rs bov, awr front motor mount, short shifter, perrin exhaust and CAI (i know the mount and shifter dont really add hp) i put down 155hp on the dyno running rich as hell. but i havent had a chance to get it dynoed again after more mods and afc.
