I can't decide on which tune to get. I have a 09 h3t alpha with adventure package. I already have the gm performance exhaust, k&n air filter and airdoc is on its way. I like the PCM because it takes into account the mods vs the superchips is based on no mods. I like that I can change settings on the superchips. Is one actually better than the other?

 

The PCM tune is a strong option, but the flexibility of changing settings any time with the superchips tuner is pretty nice.

I think it is close to a coin toss, you save a couple bucks with the PCM tune and can tailor it to specific mods, but then you have very little flexibility?

Tainter did the superchips, let's see what he has to say.

 

With the superchips does anyone ever change their tune other than when they first get it? I see that most people leave it on tow.

 

I have your mods, the Air Doc and the GM Performance Exhaust (A steal on eBay a yr ago for 200 bucks), and just loaded the Superchips. I can say, its an awesome tune, I hope you went the superchips way.
As far as the performance exhaust or cai needing to be factored into the tune...I dont know, but being able to change from 87 to 92 octane or settings for towing, thats worth the extra cash. Superchips also has a 2yr warranty on it now too.
