i thought this thread was about the superchips option? that is a cheap price for the trifecta tune though.
i like being able to tweak the tune, flash it back to stock, use the max mpg tune and so on any time i like.

I was pleased to read that someone broke away from the GM stage deal and tried the cortex. I'll be very interested in the final results. I'm totally new with this HHR deal as I only have 100mi. on a '09 SS panel,but, the cortex is on my list after I get this thing aged a bit. Hey, what's this stuff about "brake start" problems. Again, I'm totally new,but not new to cars in general.

It doesn't matter about if you can flash back to stock because the dealer can still notice the flash. Sad but true. Why not get the GM tune along with better 3 bar map sensors needed for better upgrade?

I am also scared of the Stage 1 tune..........besides the price being all over the place and iffy installations.........My dealer has done one and I ask him about it, and he said they don't like the kit.......said Chevy should provide a pre made harness, the don't like cutting and splicing.......and neither do I.
OH Well, I am not sure what I am going to do right now.........

I drove the Stage 1 and would rather put my money towards an aftermarket tune
your talking about future upgrades, those will void your drivetrain warranty just as much, since I don't expect GM to put anything else out.

Okay, mail me $100 in cash and i will run out and dyno for you ASAP and post up the results. or you can go to superchips.com and read up on it there and they have already dyno'ed the car before and after and post up what gains you get at the wheels.

It makes a HUGE difference. My friend owns a dyno, i will try to jump on one afternoon to get some numbers. it does not seem to me to have the issues the stage 1 has with the surges and power drop off described here as being normal with the stage 1: https://www.chevyhhr.net/forums/2-0l-performance-tech-46/boost-level-stage-kit-automatic-24417/ I am not experiencing any of those problems.
also, it increases the speed and the firmness of the shifts, increases the redline and that makes almost as much of a difference in performance as the power increase does. that was another big + that swayed me in the direction of the cortex tuner. it also comes with a 2 year powertrain warranty as well. You would not believe how nice the transmission shifts now, it is like a different transmission. it is really fast and smooth.
you also get the advanced tune ( where you can adjust things how you like) and an economy tune for max mpg.
it has some really cool features on the tuner that datalogs performance data as well.
