In like 2 weeks Im going to be installing 3.73 gears and mac x-pipe, and chip(to fix the speedo). My question is i can have it dyno tuned, but the guy who will be installing my stuff said that until i get a few more mods(maf, throttle body, etc.), its not really worth doing a custom tune yet. What do u guys think?? He said he's pulled as much as 30 hp out of cars with a tune, but the average is like 5- 10, with the mods Im doing. I have an 01 that is n/a, for now anyway.
