If I wanted to test for a leaky injector would it be feasible for me to enter clear flood mode by WOT when I start up the engine?

Ok, I've cut the CAT out and put a straight pipe in and it still runs the same! Dammit! the only thing I could thing of is the fuel injectors. I forgot to add that my car runs great and smooth at night. It feels like I'm Driving a cloud with a V16 engine as I pass everybody up! Tomorrow I'm going to check my MAP, TPS, Coolant Sensors, Fuel evaporative system, and IAT. If it any of these isn't the problem and the injectors test out alright then could the oil be a possibility?

Trig

Did you replace the O2? Have you been able to scan and look at the O2 for proper operation?

oh my fault I forgot. I'm finna do that right now while I got the time.
