continue with this... how about on acceleration it only smokes. Also catchcan, will this really help with oil burning?

hell yeah with the right amount of pcv vacume you can make your bottom end last alot longer and avoid narly blowby. < this is the reason im rebuilding, previous owner let the valve cover breathe through atmosphere not completely recomended

All I did was just crank a few times on each one.

yea you have to hold the throttle wide open when you crank. But thats not gonna get you another 60psi. My stock z6 was 185.

Turbo seals, smokes on decel and idle (rebuild or get a new one) off the top of my head those are the most common problems, if its not the turbo then I say get a catchcan and then run it into the ground.

You have to remove the ECU fuse and hold the throttle plate open. If not you will get inconsistant reads.

keep in mind that vitara pistons put your compression at around 8.8:1, so 110 isnt that bad. But im not really sure. It runs great though
