Well, I tested it today. It makes a HUGE difference. I put the settings at the 87 octane level with mid level options. It's night and day for shifting.

You can adjust:
shift points
Boost
rev limiter

But you cannot adjust the tire height. That sucks, but I called Superchips and they are working on the calibrations....acording ot their tech dept.

 

What type of HP/mpg improvement do you see?

 

YES !!!! I just ordered one.

 

Does anyone know if this will work on the base H3 3.7 liter engine? I haven't been able to find any tuners for my model.

 

Is there an 87, 89, 93 octane setting? Does changing the shift points prevent the early shifting, and constant down shifting when driving slow or up hills? Did they give you a timeframe on the update for the tires, and will it be an update via the internet?

 

no progarmmers that I know of. There is a pcm ugade though. Doa search on the tech section here and I'm sure you'll find a bunch of posts. I cannot remmeber the name of the manufact. or I'd do some reseatch for you.

 

The company that does the PCM upgrades is WWW.PCM4LESS.COM. I had a tune done on my 4.2L in my trailblazer night and day difference. Well worth the money

 

There is a place in Canada that will tune your Alpha's PCM, costs about $100 less than the superchip tuner???

 

Does anyone know the name of the place in Canada,that does the PCM Tune.I live in London,Ontario and wonder if they are close to me.Also,has anyone from theforum had the tune donefrom Canada.I want to get er done ! Any info greatlyappreciated.Thanks.
