POLL: GM stage upgrade on HHR SS went smooth or had issues
 

I am trying to decide on a Trifecta tune or a GM stage tune.

Please vote only if you have experience with one or the other.

Thanks

I get mine installed on Tuesday and I'll let you know.

Dealer I am going to is home of Crate Engine Depot though so they are old pros at it by now.

I had intermittent boost (full or nothing). It was reinstalled at another dealership all under warranty and no further problems.

No problems since day one

Yep, was just there Thursday. Great service and kit makes it a new car. I will have all future work done by them. They know what to do and understand customer service.


Hint: Go to a Dealer that knows what they are doing. I did not go to who I bought my car from. I saved $150 in doing so and had it done by someone that's done it many times. I would have been paying for their training and I would be at risk of their unfamiliarity of the install.

Had issues with the first dealer. Then went to an experienced dealer and it's been rock solid since.

Did the second dealer say what they found wrong? What did they actually do?

Installed a new kit because they did not want to take the time to check the wiring connections. The tech was mad because I had it installed at another dealer so he complained about the whole install. But it is working now.

No problems so far. Just smiles. Props to Henna Chevrolet in Austin.

i wish there was some way to check which dealers have performed installs by state other than calling all of them lol.
