I know this has probably been asked time and time again but what is the best PCM for NA applications?

The absolute best would be a custom tuned one. Second best would be an Intense-Racing off the shelf and customizable one.

not wanted to dash your hopes but staying NA is your biggest failure.
the money would be better spent saving up for a sc swap.
honestly i doubt you'll ever hit 250whp na and if you did that would be after 5k in mods.
i'd either swap or buy a new car which may be easier unless you have skillz in it.

you stock pcm is probably fine unless you decently modded.
what mods have you done?
why do you think you need a pcm?

well i sure dont have enough money to get a top swap, i just want something that will make my car have a little more pickup, im tired of having to floor it just to pass somebody.

honestly a pcm and cai will do very little for the engine.
like maybe 10hp peak.
it'* going to sound faster, and shift firmer which will give the illusion of it going faster but in reality you will be within a .1-2ths of your original 1/4 time. if that. i'd save my money, sell the car and get a ssei and start there much cheaper per hp. but do what you want...

i was also planning on getting a ported lower intake,a powerlog, and a high flow cat.
