well I just bought it,anyone know what the diff is between emission models.any downfalls,and if so can it be changed,and would it affect warrany,received a 12 month 12 thousand mile bumper to bumper,btw i live in mn,no emission checks

 

don't think there are any differences, except maybe in the cat. If you have no emissions, get a catless dp for sure, charge piping, ic, and tune the hell out of it!!!!! mo boost!!!!!!!!!!!

 

would these mods void warranty?any advice on companies,gm stage 1,hahn,hp?done a lot of reading on most of these,some say gm tune your stuck with if you do this,some say you can add on top of gm tune,whos right?

 

From what I hear, you can't go wrong with Hahn

 

Just about any mod could void your warranty, some guys get around it because they have a great relationship with a particular dealer, but even those have been known to go in a bad direction..... Other than the Stage 1, I would wait, or if you can't wait void the warranty.

 

First I do believe you should have the 100k warranty through gm, as I believe this is transferrable. So to have a warranty offered through the dealer who you purchased it through would be a bonus and as far as that warranty is concerned, I suppose it would depend on who that particular warranty goes through.

gm stg 1 is a great starting point, and retains your gm and should retain any other warranty I would assume. If that is not enough power, yes you can tune on top of the gm stg 1...you could have Trifecta do a tune on top of the stg 1, or do an hp tuners tune on top of it as well, although I am not sure what gains are possible having the stg 1 with a tune on top will actually give you vs. having only a tune??? Additionally, the Trifecta tune can be turned off and hidden so the dealer won't know it's there.

you do need a tune if you add any performance parts as the ecu has a learn down feature that prohibits adding go fast goodies.

options, options, options...Good luck

 

Thanks alot.This site is great,sounds like trifecta tune would be better than stage 1,do you know how much and where to order?

 

you have a pm
