What that little and very old phrase means. Lets go to a car analogy ( forgive me ).
I have a plain Jane 2001 Neon SE 5spd MATX.
Now in it's stock form the car is a rat, for instancee 1st gear is a very narrow band and sluggish as well as second........the car wakes up around 3rd and 4th gear.
Now if i wanted to improve the performance of the car the right thing to do would be work on the areas it is weak. Installing long tube headers and a CAI and a cam would be counter productive as those 3 things would boost mid range which is already preety strong.
Cost for above mods would be roughly $600 with quality parts.
The logical thing would be to install an under drive pulley for faster rev, alum flywheel, and dump the stock 2" exhaust from the cat back which would all boost the bottom end performance around first and second gear.
Cost for above mods would be roughly $600 with quality parts.
2 totally diff paths of upgrade pointed out above and tbh would you feel the difference? Not really, but it would be measurable and the last one would net better measured performance.
Make sense now?
You can tune deffencies away whether it be a cpu or an entire system build, it all just depends on your end game or goals and choosing correctly. It's always better to tune for some nice balance in the end.
