Yes you can...
Gm doesn't lock our tunes like they do on the Cavaliers.

Worth it all depends what your end goals are. I guess if you eventually want to get more than what you got now then,... yes

I've has 3 or 4 different tunes on my 2.4. Started with Werks when I first started modding, then DDM Stage 2, then DDM stage 3, then finally got around to calling Lyndon. Glad I did, as it has never run so well. Westers is absoultely the cats meow.
Depending on where you are, he may have a remote agent who can data log and install his brilliant tunes. I was lucky to have this and went through several iterations to get the sweetest results possible.

Sure - and I think more than a few people did that so they could run the GMPP when they took the car in for warranty service, and then hit a button and switch to the Trifecta when they left.
As warranty will run out on even the last cars this year, there is less point in going that way - may as well just go to the Trifecta right off the bat.
As for other than Trifecta, I don't think anyone else has the ability to switch with a dash switch. Correct me if I am wrong, but I beleive that you have to load the tune again to switch to Westers etc.

What most of the members here need to understand is that probably 90% of the aftermarket tunes are based on the GMPP tables and then they improve from there.

PT, it sounds you're happy you made the switch performance wise, but how did you justify it financial wise? Isn't the money it costs for the GMPP basically being thrown away?
Too bad the GMPP software can't be improved to equal the aftermarket tunes.

If you 'improved' the GMPP tune it wouldn't be the GMPP tune any more.
The other after market tunes simply replace it. Like I said, they only one that reside sin a different area of the ECM is Trifecta - with that one you can switch between whatever your base tune might be and the Trifecta tune, by pushing a switch.
But we are swiftly nearing the end of the time when anyone will care about switching anyway, as warranty runs out on the last cars this year. Just buy what you want, load it and forget about it.

Hey Chop, I understand what you're saying. If that's what you wanna do, my suggestion is to get HPTuners and play with variables one at a time until you're happy with what you have and something that won't wreck your motor. That will be what I think I will probably wind up doing this next fall. I really want a dyno tune, but I don't want to spend $1200!!! LOL.... So I will "dyno" it myself with a recorder and make changes....

Agreed, I went from the GMR to Trifecta with much the same results.

One thing I liked about the GMPP tune was no lift shift. None of the after market can add it. They all work by modifying the either the stock tune or the GMPP tune. It also comes with CARB sticker that say's "turbo charger upgrade" that may become very helpful at smog time. I thought someone offered a switchable HP tune. I looked and couldn't find one, it may have been Dejon, but I don't think so.
Not necessarily. I still have the upgraded sensors which provide some extra headroom. And I liked having the NLS there (which the GMPP gave me) even though I haven't used it much...
And Lyndon was having a special that weekend at the show...
Also, as I recall, Lyndon has figured out how to speed opening of the throttle body which would be a gain by itself.

L-N-F'n, with the mods you list in your tag line, when you switch your tune back to stock (or whatever it is) can you legitimately pass the CARB smog test? PM me if you'd rather not respond here. I am considering a Wester's tune.
Are you planning to attend NASSM2015? I plan to be there.
