im gettin dyno tuned on monday after i install my 60lb injectors and i was wondering what kind of things i should ask for when i get tuned cuz i know i have to turn off my rear o2 sensor, but i wanted to have it where the fan comes on sooner and maybe a 7250 rpm rev limiter... if i do that will i be ok with the stock valve train?? thanks guys and any suggestions u got let me know! and i will post #'s and a video if i can!

 

delete the speed limiter too!

I dont think i would run it above 7000 RPM

 

thats a given

 

I got my cobalt tuned and the tuner told me he did not change the rev limiter because it stops pulling after 5800 rpm so i had him leave it stock.
