The ct9 doesnt have the kick in it or pull as hard as the tf035 though It also start running out of puff in higher revs at 1 bar, maybe not the hybrid but then they are more expensive If i had an ebc i would have pushed it more to maybe 1.1 1.2 but mike at td said it wouldnt be far off what my td04 was running 1 bar It all depends on how you prefer your car to drive and im happy with the tf035
