hello i have a cobalt 2.4 ss
and i would like to know if there is any chip
i and install on my car to gain hp

 

why did you just make a second thread thats exactly the same as your first. you are like the 3rd new member to do that this week. there are no chips. look up trifecta for a tune

 

You silly canadians.

 

Go with HP Tuners. If your an 07 down they have support and if you are an 08 then support was just released.

 

the plug-in or piggy back chips dont make alot of difference.. It cost more, but a dyno tune would make the most difference.

A Gasoline engine requires three things (Air, fuel, and spark)
I would get a quality cold air intake, free up the exhaust and then have the car dyno tuned. Those three are your best bang for your buck..

 

Thx for the advice
I hv the cold intake im in process to get a exhaust
So whats the best exhaust i can get?
And the sparks whats the best?

 

Chips are food. No one has used chips for tuning in forever. We use laptops and special software to custom tune cars.

 

The Brand of exhaust does not much matter. As long as its 2.5 mandrel bent... 3 inch is too big for a NA motor..
Magnaflow makes a very nice cat-back and sounds good too.. If you want something loud go for a Megan cat- back
With a cold air take and any aftermarket cat-back you will be at the limits of the stock tune.. If you want a dyno tune and dont mind picking up some extra noise get a downpipe with a Hi-flow cat built into it.
A header does not do much on a NA 4 cylinder.
