Some tuners can tune throttle "tip-in" but I was told not to tinker on my own.
I looked into a HondData for my R18 and I understood for the device to work, the engine has to be modded in some way (turbo, CAI, super, whatever). Of course, I could be wrong. I never pursued it b/c I use my car heavily and don't want to give up the 34-37mpg I get on the highway. Those devices are regularly on sale in the 4 sale section.Can tuners even tune a bone stock EX or does it have to be modified some sort way?
