Yes, these are night and day compared to T34, people do not believe the hype but they transform the engine and the power they make is fantastic. The low boost map felt quicker than the T34 and was probably producing less headline power but still had 420 lbft of torque and that coupled with the quick spool up made for a much faster car. I cant wait to try the high boost once the close ratio box is in, it is going to be a rocket ship.
