Advised on the first upgrade mod!!
 I have a couple questions if someone can help me out I really would appreciate it.
How much horsepower do y'all think that I will get when I install a 2.7 pulley with 80# pound injectors with a smaller belt and a Sports performance radiator. Also a header/down pipe with srs type-r1 catback exhaust system. However I've been doing my research about running a 2.7 pulley with a smaller belt that you have to have secondary reservoir and a dual pass.

Really need more information to gauge what you would put down. Typical stage 3 cars put down 250-260 on pump. Are you on E85 or pump gas? You won't need 80's on pump. You would get a better idle out of 60's. Are you getting a custom tune or canned tune? Also what is done to your car currently.

I currently have just a normal set up on the car for a 2006 Chevy cobalt SS supercharge 2.0 L Engine. For gas I'm using premium and for the tuning once I find a decent spot in Maryland I'm going to it.

I don't know of anywhere in maryland, but SMG Motoring is in Mass. Since your car is stock have you read the LSJ modification guide? It is a sticky in the 2.0 LSJ performance section.

260 or so whp if your car runs well, is tuned well and you can keep your intake temps down. Definately add a dual pass and option b to your setup. Really these cars should have those mods on the stock pulley.
And no intake? Look into the 'stock airbox mod'.

I would recommend grabbing a tuner from this forum though, they can remote tune you if you have the cable needed. Most don't recommend going to a shop for a tune UNLESS they are familiar with LSJ/LNF.
