Just remember The only present Custom tune that produces more than 300WHP is the Trifecta Tune. The SS Cobalt with the Trifecta Tune runs faster than a known Hahn tune in Ohio.

With that, Standard HHR and SS non Stealth Tunes are $200 plus loaner shipping.
The HHR SS Stealth Tune is $300.00 plus loaner shipping.

 

I beg to differ Tom.
Livernois Motorsports actually has one running 325hp.

http://forum.grrrr8.net/showthread.php?t=6538 But a little low on the TQ at 258

 

Ok my understanding of how to make a dual tune is to have a seperate connection running seperate from the ECM. So is there a perminant connection to the Trifecta tuner? Can't flash the computer without it being traced.

 

Ok that is the first I have heard of that company, so of the tunes discussed here I could say.

 

The complete tune is in the ECM, the Trifecta Tuner is only used for uploading and data logging.

 

Yeah, livernois is not much known in the 4Cyl World. They are more specialized in Mustangs and LSX motors. They are good with tuning abilities though.

 

If the cobalt ss and hhr ss are the same motor, why isn't the tune for the hhr the same. i'd think if they were the same the tunes would have come out at the same time. essentially it's just a different body right?

 

But is their 325 on a stock motor with no mods? and you mention not known in the 4 cyl world?

08redhhrss, the tune is used on both. Same engines.

 

so why is it new and just released if its the same? We just heard about the tune for the hhr recently and the cobalt one has been out for awhile?

 

Livernois is a very widely know shop for V8's. They've done some high end jobs too, like Paul Tuetuls from American Choppers Z06 etc
