Default Runs weird

So awhile back I built a motor and had it tuned. I don't think the tune was to good it bucks at low rpms around 20-30 no matter what gear. sometime it run great and sometimes it doesn't want to run worth a crap. It doesn't die or surge. And it has a very slow throttle responce. It runs great over 2000 rpm must of the time. This is a list of what I have done it's a 01 t/a m6 with a lq9 short block and ls2 heads cnc'd. Magic stick 3 cam at a 111 lsa ls6 intake p&p'd throttle body lt headers 25% underdrive crank 10% overdrive alt pulley. And has 32 lbs injectors. Like I said sometimes it runs great-ish and most of the time runs rough. It doesn't throw any codes ether.

Data logging is the first stop... Until then, it's only a "SWAG"....
