Well I did a compression check on the motor before I went with boost.And I have put about 500 miles on their with 7psi boost queit regularly. I shift at around 4500 rmps under boost Because im running factory everthing! My plugs seem to indecate that im running rich How could this be with factory fuel pressure and only 180cc injectors. But this is how the check came out

1 180 psi
3 177
5 180

2 177
4 172
6 177

Standered is 172psi with a max diffrance of 14psiper cylender


So I take it my motor is still in good shape
It has 169,000 on it
