I have a buddy with a 2006 cobalt lt. He found a good local deal on a lsj part out with a few zzp goodies as well.

Now the problem were having is how he can go about tuning his cobalt for the upgrade. I've study the swap for jbody cars since I have an 03 cavalier I want to do as well. However it seems from my research that the 06 ecu isn't supported by hp tuners. I've checked with zzp and they can only do 07+ ecu's.

I'm wondering what options we would have to tune it then? I know he could use a Trifecta flash, but seems the only recent info I can find on them is slow response times and unsatisfied customers, despite I was given a quick response when I emailed them about it. Are there any other options for the 06 2.2 cobalt for tuning?

Unless something has changed in the last year or so since I looked into it Trifecta is the only option for 06 2.2's.

trifecta has a bad rap...but it's not all bad. many ppl have nothing bad to say. climb is a good guy to talk to if you want a good review. trifecta is really his only option unless he wanted to rewire to an 07 pcm. its been done by somebody. don't remember who or how much was involved but i'm guessing a good chunk of work
