Yes, it is a direct bolt-on and NO it does not reduce low end TQ. It improves it! A LOT! As for RPM's, I see less at the same speed now due to more power! And no, I don't have any dyno runs on this mod. If I did dyno runs before and after every mod, I wouldn't have the $$ to continue modding
The last time I dyno'd I was at 211WHP and 246WTQ on S0(stock PCM) and 1/2 the mods I have now. I really do need to get some new #'s.
The sensors are a 5min deal, very simple as is the whole replacement. I would recommend the plastic intake manifold upgrade to go along with this TB change.
