pulley and injectors.

[lebUNIT]

Hey guys i bought my car around 2 weeks ago, and i feel its too fast to be only stage 2. It says on the pulley 77.9 . i wanna know what size is it( 2.9 or 2.8) and how can i find out what size of injectors im running. Also, how can i know if im tuned or not? any guesses and suggestions are appreciated.
thanks guys
couple pics if that helps.

going from my own experience your gm stage 2. running a 2.9 pulley 42.5 injectors.

Get a intake to open up the intake side, header/dp/2.5 exhaust get tuned by Matt from Edmonton. and you'll easily see 280 hp also add a stage 3 heat exchanger/ option B and you can get a single pass to really cool off the M62.

By what I see I would believe that the above statement would be correct as well as his recommended upgrades are good choices.
