I have a 2006 2LT HHR with the 2.4L engine. I installed the cold air intake with a set of E-3 plugs. Still need some help to increase HP without killing my MPG, looking for suggestions that work?

 

Welcome to the site Wingman.............There are many thing you can do. CIA,exhaust,Trifecta tune would enhance performance.

 

Left it at home in the nice, dry garage...mostly because I'm too lazy to switch the car seats over in the rain :) Rockin the Lumina and all it's squishy glory.

 

drove 3 kids to daycare.... ya know the normal.

 

@Wingman, Trifecta Tune is what I hear that is good.

 

I've been rocking the Lumina since September...nothing wrong with that!

 

As soon as the HHR is paid off, the Lumina is a goner! I'll make you a deal Eric so you can have a fleet of Lumina's :)

 

Then he would have to start his own forum....

 

No no, 1 is enough...

 

Hey now, the in-laws owned a Lumina that just wouldn't DIE... Damn thing had close to 225K miles on the clock. Body was crud, but the motor was still smooth. This coming from a die hard Mopar guy, converted to the Chevy side o' the fence.
