Don't post often, but figure not many pictures of GMC with soft toppers, so who not

Very interesting. If I were to buy a new GM truck I would lean towards the 5.3 still. Its what I have now and would be skeptical the lower HP/TQ numbers than my current 5.3 would satisfy me enough to go with it. I have yet to drive one, so its possible it would preform just as well as my current 5.3 but I don't know. I think a lot of people will focus on the peak numbers, and if it were me I would bump up the size a little to get the HP and TQ near the previous gen 5.3 engines. I like how it is meant to run on 87 octane but wonder if they will have the ability to detect higher octanes (or even E85) for a performance boost?

Thats sort of what I'm hoping happened...but if it happens again its not a cheap repair...

First post here, been doing a lot of searching and reading on this site, but couldn't find an answer related to an issue I had. I recently bought a brand new 2015 Sierra 1500, SLE, 4WD Crew cab, 6.5' bed, to replace my 2004 Chevy Avalance. I had the curtain airbags deploy on me while on a mountainous road, bumpy, ruts, and side angles. GM is fixing the issue once on goodwill, so it is taken care of. So my question is there a way to temporally disable the airbags or curtain airbags (GM won't answer that obviosly)? From what I read, the new trucks have more electronics intergrated, and its no longer simply pulling the fuse marked airbags. Manual doesn't show any "airbag" fuse. I was thinking there may be a fuse, but its no longer marked "airbag." They weren't certian if shifting into 4-HI or 4-LOW would change the parameters for airbag deployment. If there isn't really a way, I'll try to get some answers from GM on more specifics on what will set it off... is there a minumim speed? Angle? The represnetative made it sound like there is gov't specs on when curtian airbags will deploy in a rollover, but I thought it was more proprietary to each company? I don't plan to 4-wheel my truck much (I have a RZR for that now) but it is nice to be able to 4-wheel to a camping spot or somthing like that every so often without worry of airbag deployment. Thanks, Sterling
