After the tweaks you are getting a higher air flow at the top end, which would suggest more power. It is the torque that you have lost; but this is good for the life of your rods and taming wheel spin I'd say
Air flow is the same Danny, i consistently log between 200 and 210 g/s.The toruqe has gone on holidays, luckily if it hits 260lbft these days.
On another note because i am now running low CF's i wonder what effect pushing the timing on a bit would have? Would still help it get some of its grunt back?
