Good morning!
If one were to upgrade their base level C2 with performance bolt-on upgrades with a combination of headers/intake/exhaust, would a tune be required to bring the cars potential up to par? I understand the cars ratios might also be affected. Assuming no CELs are tripped and the car responds fine to the upgrades... I am asking purely on the standpoint of bringing out the cars potential from that point forward.
I also understand building a vehicle like this would only be legal for track use and there are street legality issues, etc. etc.
