Tuning after header installation???
I asked for a quote on getting the car tuned after header installation.. and was told dyno tune for 400..
my question is does the car have to be on the dyno to tune it for just the a/f ratio change or am I just retarted
I remember reading somewhere that you shouldnt waste your money on o2 sims case you can just have em tuned out after your installation for like 75 but now that im typing this i see that it may just be 75 to delete the o2s hmmmm Trending Topics
