I've got 5k's in my truck and i think they are coming out for some 4ks...id like to have the ability to turn over 4k but the streetable part is more important to me right now. But what i have been doing for the time being is holding my foot on the right side of the throttle on the firewall and rolling my foot into the throttle vs just having my entire foot on the throttle...taking like you said is by the far the worst part and i have to be super careful or it will jerk and bounce ungodly terrible.
