Their tuner used HPTuners. I'm sure the Cobalt guys see this as ordinary but this is downright impressive with just a tune on a stock car.

The final tally with more boost and timing is an impressive 278 whp (5,600 rpm) and 300 wtq (3,000 rpm), far greater than our baseline of 248 whp and 251 wtq. That works out to a gain of 30 whp and 49 wtq. The peak gains are one thing, but also check out some areas under the curve, which are 50-60 whp better than stock.

Issue? Print? Magazine? What's that?

Other turbo and direct injected engines respond ridiculously well to tuning so I'm not too surprised about the gains. Just awesome considering this thing is priced so cheaply and responds so well to mods.

Tunes are the single most bang for buck mod out there for cobalts. Trifecta has been busting out tuned cobalts one after the other with around 310 whp and 340 wtq with only a tune. I probably should get off my ass and get one.

seems about right.


same thing for the SS/SC... my car... GTOs...
Not even close:rofl: A stock ss s/c thats tuned MIGHT pick up10whp tops! But then again via tuning they can up boost we have to swap pulleys

Waiting on the SRI from ClearImage Automotive to come out and the new map sensors from GM if it ever comes out.
they just released it going for $195 if i remember i think they might have a GB on cobaltss.net im looking to get this and the trifecta tune also but i might have to go with the gm stage kit or nothing while im at school to keep up the warranty
