Is your transmission or torque convertor shot?
I assume you have a automatic transmission.
+ or - 0.5 volts on your MAF air flow is a huge difference. Expecially with the 3" intake piping. Plus if your boost is low, I would automatically be looking for a boost/vacumn leak in your couplings/connections or the boost relief valve could be sticking.
