I dunno... 1.5 bar is like 22psi. First off, thats past the efficiency of the turbo so all you are doing is pumping hot air. Second, you are most likely detonating and the timing is being retarded to hell and back. 22 psi on 93 = on a T28. Really should only go to 18psi(ish) max.float_6969 wrote:WRONG!!! It's 15 degrees for the CA18DE, it's 10 degrees for the CA18DET read the FAQ a little closer.
BUT, I don't know that the extra 5 degrees would cause that much problem as long as you're not detonating.
