In regards to the GMS1 tune, I understand it's a "canned" tune and the way I understand it, the GMS1 doesn't play well with bolt ons. Is this correct?

I was planning on buying some go fast toys for my 2010 SS/TC, which already has the GMS1. Should I even bother? Perhaps I should go in a different direction until the warrenty expires?

Thought I should clarify by "play nice" What I mean is, the GMS1 compensates for any gains provided by the bolt-ons.

 

I have been wondering the same. I have GMS1 and wanna do more, but wanna wait till after warranty.

 

I noticed in your sig you have the ZZP catted DP. Did you have that before or after the GMS1? If you installed it after did you notice any peformance gains? How does it sound?

 

U should see some gains. But not as much as trifecta and hp tuners.

 

if your going canned do the zzp canned tune with the GMS1 3 bar map sensor included... They will send you the maps and sensors then you have a zzp tune with the bad ass maps and sensors... I was told are sensors only read up to 24.7 lbs then it starts to get shady.. zzp canned tune with senors then a hp tune!! FTW
