Talking about reprogramming the computer, the only mod that I can think of that needs a computer reprogramming is a smaller pulley (if there is anything else let me know) Moreover, even if I get the computer reprogrammed to handle the smaller pulley and increase the rev limiter, will the check engine light go on and how can I avoid this. I ask this because most YouTube videos I see of modded Comp G's that have smaller pullies seem to run fine but in mostly every video, the check engine light is on.
I already have the shop in mind that does this kind of work and they are legit too. I will include a link in this post but can I just brink it to a car mechanic too? Headers I am also looking into doing since they sound like a good idea especially since mine are all rusted. I am just fearing it may screw up the sensors as this goes with the intake as well. Also, if I do this, will I have to worry about that aluminium around the headers being removed or will they unnecessary?
