you can feel it in a straight line, but it wont help your car turn any better lol. 5.5 car has the same amount of available traction as the 17.5 car. always a compromise to be made somewhere. boost can really help a lot on the feel aspect. you can tune your throttle curve very nicely with esc boost to take some of the edge off a hot motor. of course, you can never use the throttle like a light switch like in stock.
