ive owned my evo for a about a month and i did my first round of mods and had it street tuned on evo scan within the first week. i wanted to know how they respond to small changes. like for example if i were to upgrade my intercooler would my car not run right? ive heard these cars are super sensitive and that once its tuned if one minor thing is changed the car will run like complete ****. so far i have a samco intake,upper and lower hardpipes,evo IX bov,3in turbo back exhaust,1000cc injectors,255 fuel pump,act stage 3 clutch,hbc manual boost controller,and aem wideband w/gauge.
