How much of a gain should i see if i get my comp tuned for headers, cai, no cats, and 3.73 gears.... Should i just wait for a cam to get it tuned because my speedo is off bc of the new gears.

 

I have read gains of ~10rwhp from a mail order tune, with dyno tunes obviosuly higher which is what I would recomend you get when you install your cam. I would just spend the money to recalibrate my speedo for the new gears for now (on the mail oder tune)

 

Not to mention some other benefits off reduced running temps and more aggressive tranny shifts.
