Hi I'm quite confused I he s16 which made 168bhp 140trq with k&n air filter, straight decat exhaust, at Sanspeed on there Bosch style rollers,
I now have pt2002 kent cams and blackbird 1100 throttle bodies, re-map and same exhaust system, which made 153bhp 140trq on sanspeeds dyno dyanamics rollers,
They done the cam timing aswel, they said the dyanamic rollers read low but seriously how low could they read? the car does seem to be faster and pull a lot harder, I have the gti6 gearbox aswel,
I know I'm low on compression but I was low when first had my car on the rollers,
Can anyone help or have any suggestions on this?

Low compression + uprated cams is not a good combo.

Yep, you will definitely need to have the compression back to where it should be before the cams and bodies will complement each other and make your engine develop more power. Yes
