A friend of mine needs to tune his evo so he can unlock its potential. what part in the program do you adjust? I forget because the last time I seen it, it was about 9 months ago. I know its a 3rd gear pull but what rpm do you accelerate at? I know a little with tuning without a dyno but has anyone here done it and if so if you have do's/dont's or just advise plz let me know. Right now thats all the Q's we got. Thank you for the help.
