i have a 2005 zx3 2.0 auto with a fswerks race exhaust and col-flo intake. also changed the plugs to e3. other then that my engine and trans are stock. im thinking about getting a sct tuner from fswerks. im looking for a little more power and a little more mpg(i know its easy to say and hard to do) but just have my car run better all the way around. was thinking a 91 octane tune and and maybe some other stuff but i thought i would post on here before calling the guys at fswerks.

i don't know much about tuners so im looking for some help and ideas.

please help

No need to touch injectors at all until you go forced induction or big N/A mods. You can run a 93 octane tune on a bone stock car.

FSWerks is regarded as one of, if not, the best guys to tune the car. Give Randy a shout and he'll get you want you need.
