Ok guys, I know there are alot of you (if not all of you) that know the top things to do to the 09 Cobalt SS turbo that gives you that kick to make your smile go from ear to ear. Im looking to do the same to my car as well, but I just have some cosmetics that make other tuner guys get intimidated when seeing the halos with the 8000k fog lights that just makes them think im pushing something. Well now instead of me just hanging back when they speed off wanting some, I want to be able to walk the walk as well. Dont get me wrong Ive race plenty of people but i try not to pull up against others at red lights and reving crazy style to get there attention. What are some GREAT things to do with the car. I have the GMst1 ECU flash with a Injen INTAKE but am thinking of going HAHN all the way round with the full blown exhaust, Intake and Charge Pipes.. Good Idea? any problems with HAHN except for there outrageous prices?

Ok, well I already have the GMst1, how much more could I get from another tune, Yes I know when i get everything done I should get a tune again. But the car does learn a little bit about what you put on it since its able to see what is going in and what is going out ,ect ,ect. I seen the ZZP tune and it seems good but like i said how much more would i get after the GMst1 because they are basically the same (ZZP claims more HP but no trq spec, while GMst1 is warrantied and need 93octane). Thanks again

93 Octane gas is necessary for all the tunes out there.

Do yourself a favor and look into other companies like Dejon and ZZPerformance before spending loads of money on Hahn stuff. Their stuff is nice, but other companies have just as good quality for a LOT less money.

I'm sure a ZZP tune or Trifecta tune would yield QUITE a bit more power than the GM tune... I've never had it, but others who have said it's a huge difference...

I have the ZZP tune, full 3" exhaust, intake, and upgraded intercooler piping....HUGE HUGE difference over stock!

Dejon!!!

Hey does anyone not like Dejon for any reason. They have resonable prices for everything. Like any one else to say good or bad about them!!!
thanks
