Ok so, if I were to get a cold air intake on my car I know it does not really give any sufficient gains. I was wondering if I had gotten one and maybe injectors, with a tune what power gains would be in the results. Also when people say "tune" does that mean a full dyno, or programmer and what would be the best one to do. All im looking for is some help with this, Thanks
I know someone who gained 8 whp from a tune on a bone stock Ecotec.
So from a intake and tune likely 10-15whp gain.
If it was me I would do a few other mods before getting a tune. Chances are you are going to do other mods. Unless you are doing it yourself or have a friend doing it for free.
