well as some of u know i was testing the first sps manifold. i got the manifold at the start of the week fitted it and rite from the word go the car felt much better all so did not boost creep as much and seamed to hold boost better. i made it up to the dyno to day (seam one i was at 1 month ago)a alot of NI guys use this dyno and it is trusted. the red lines are the manifold fitted and the blue is the stock manifold . note! that it was not holding boost v well the first time(old manifold) so i had to run a lot at the start( that y the peek torque is v low) then it droped off but stayed at 14p
