LMAO...another one that knows more than the rest of us. I run the sprint booster, which does open the throttle up instantly, and does nothing more, and no, regardless of the bullshit conversation here, a tune will not accomplish the same throttle response. If you don't like instant throttle, then don't buy it. The tune will increase HP, and will from perception, eliminate lagging throttle response. Quicker throttle, quicker quarter mile times even if only a 1/10th of a second. The rest here, is just plain bullshit. With the SRT's, it can be a pita if you aren't used to it, but I love it. You just have to learn to be ready for it. I can't say what the difference is in the N/A version, but I would think it would react the same. So, bottom line, if you don't like it, don't buy it, but sure as hell don't talk like it doesn't work or doesn't improve performance. Performance isn't always measured in HP. It can be measured in reaction time. If you don't race, don't buy it. Our tuners are good, but some things can't be tuned out, and movement of your foot wasn't included in my Eurocharged tunes. Jake can't do it all....lol.
