Well I've been having problems with my boost as shown here...

Trying to do research on it...

But my question on continuing to figure something out...

Can I switch from the GM Stage 1 to a trifecta tune? Will that fix all my issues?

What's the costs? Installation?

 

I was wondering why you haven't done that yet. I suppose that would depend on what is really wrong, it would be nice to have GM get it right for you first, Trifecta or not you could ask Vince he would know. vince@trifectaperformance.com

 

That's my concern. If I tell GM to stick it where the sun don't shine... give me my stage 1 costs back. Would there be an issue to go to Trifecta? It's hard to say I'm sure not knowing what's wrong.

That being said... I've also been researching replacement vehicles as well.

 

If I replaced it I want another one. Give Vince a try, would you like it if it held 26lb boost ??

 

I might like that.

I don't want to waste his time. Who knows...

I guess if they determined it was a stage 1 problem then the Trifecta should fix the problem.
