i need to know what options i have for the ecu in my 07 cobalt ls.id like to remove the limiter and tune it for stage 2 cams.ive yet to find out if they can be reflashed or if i can find and aftermarket unit.any help would be great.

 

Trifecta Performance did my tune. Everything in the computer is different. It is a real tune just as if you would have bought LS2 Edit of HTP tuners.

 

is the ez flash programming cable worth it.which would you recommend without boost?

 

Ez flash cable is the cable that comes with the tuner. and that is used to talk to your computer in the car.
I dont understand what you mean "which would you recommend without boost"

But i can tell you vince is the only Programmer that has tuned the cobalts with cams

 

is there more than one uprade option from trifecta?

 

you can purchase the Gt tuner and trifecta ships it to your door with a base tune on it. then you call vince after you put it on and then he'll walk you through how to data log it so it can the best tune as if your at the dyno
