Heres all the new stickers that come with the kit:

 

Question... Does the stage kit eliminate the restriction of HP on the auto, bringing it up to the full 290hp like the stick or only 30 more hps added to either the factory spec of 250 hp or articles specs of 253hp?

 

I have it in an automatic. While I can't say for sure that it is even with a stick now, as I've only been in my hhr. I can admit to peeling out from a rolling stop without meaning to. It drives like a completely different vehicle now. It's a night and day difference for me.

 

The Automatic with the GM Perfromance Parts Turbo Upgrade kit has the same HP and Torque as the Manual. So the Automatic gets 55 HP and brings it up to 290 HP.

 

Hey, I didn't get one of those! I opened my box, so I know that no one at the dealership took it! Is this something new?

 

I got one with my kit in Dec.

 

Thanks for the answer

 

now with the auto you lose 15 to 16% in the drive train where the standard only loses 6 -7%

i have the auto with stage kit and love it.

 

I, and probably a few others might be wondering - is there an update to this? Curious to see how flat the torque curve is. Thanks for all the info you have provided to us!!

 

But that is offset with the tq mutiplication of the tq converter...
$10 per HP gain..now thats a deal! Before you could only get that with chrome go fasters!
