well guys, (mods feel free to move if this is the wrong section)
i had my car dyno'd about one month ago and it has 228whp and 197tq. eveyone is saying that they are getting about 35-40hp with stage 2! do you think i would get the same or do you think i would just gain about 12-15hp. now for smoe IMPORTANT INFO!! once i got to about 3500 miles i noticed i was only hitting 10 punds of boost. i then tookit the dealer and then they fixed it! not exactly sure what they did butnow i have 12.5 punds of boost. is there any way my gauge could have just been set wrong so all they did was turn the boost up somehow! i will post up my dyno sheet as soon as i find a friend who has a scanner, and if i can't find anyone i'll take cell pics of it! thanks alot guys.
im just trying to figure out what im buying myself for christmas.

If wanna keep your warranty, buy stage 2 then buy one of those 2.8", or whatever the smallest size you can find pulley rings that will fit on the GM hub. It will give you what your looking for me thinks.

 

You might hit 260 on the dyno with gm stage 2, 2.8 pulley boys pulley, intake and exhaust...but i wouldn't say that was a conservative number....
