01 Cobra emissions issues

I have an 01 svt cobra with 26k miles that pulled a p0174 code. I had both o2 sensors replaced and fixed a vacuum leak at the maf sensor. It has a c&l intake with a granitelli maf 90mm calibrated for 24lb injectors. Also running slp loudmouth cat-back. Any ideas on why I keep pulling this lean code? Also a new symptom popped up after the o2 sensors were replaced. After about 80 miles of driving it started to give a puff of white smoke at startup. I checked the oil and coolant, both look normal. I think the smoke is excess fuel possibly from the ecu telling it to give more gas that is just not bring spent in the combustion chamber. Any help will be greatly appreciated.

Thanks, Zach
